• is this already open source, do you have a link to the source code?
• is there a schematic available, also link or attach it - this helps a lot or contact Vendor and ask for schematic.
• which exact main MCU chip is used in this?
• currently IronOS works on BL706, GD32VF103TB, Stm32f103 MCU chips (easier to port IronOS if same chips).
• do you have a link to the company specifications for this model?

[Syncmasterklop]

I received this soldering iron, it looks and works very well.
Manufacturer - Fnirsi, I wrote them a letter about the circuit and source code, but there is no answer yet (most likely there will be no answer).
The main chip is CH571F, you can see it in the photos.
There are no specifications from the manufacturer, there is an instruction where you can see something.

[Ralim]

Until manufacturer is willing to provide a pinmap or schematic support isnt going to happen sadly
That MCU can definitely run IronOS from a specifications perspective but without schematics its just too much work to reverse engineer at the moment.
You are welcome to try and get in touch with the manufacturer and find out if they are interested. If they are willing to help with providing information for porting then this can be considered. (If you get an email contact, feel free to include me in the email if they are ok with it).

I've also sent a message to Fnirsi outlining why IronOS support would be beneficial and the fact they don't have to share the entire schematic, but just the relevant parts. Here's to hoping they realise the marketing potential.
The hotend cap is a really standout feature for me.

[Careless]

slightly off topic, but can anyone measure the HS01 iron without the hot-end cap?

The measurements i see online are 184mm x 20mm diameter from end to end with the cap installed.

i don't have a need for the cap, but my case I use for storing all my equipment has 170mm column slots. if it fits without the cap, that'd be great.

also if anyone can measure the LxWxH of the included PD65 watt charger, that would be much appreciated. Not much info on these units yet.

[0x4C4A]

Forgot to update - Fnirsi wrote me back, unfortunately they were not receptive to my reasoning that releasing the schematic would be beneficial.

Hi, dear friend,
Thank you for your support to FNIRSI and your suggestions,
It's a pity that the schematic is the engineer's secret, he didn't share it with us, we can't help you.
Thank you for your understanding,

Perhaps more messages may make them reconsider, but for now, it looks like reverse engineering is the only way to go.

@Careless
The length depends on the tip used, the iron with my default tip (HS01-B2) is 176mm, with the longest - the thin tip (HS01-ILS), it goes up to 180mm.
I have the EU power brick, and its dimensions are ~90.1mm from prongs to top, ~53mm for just the brick from bottom to top (not counting the prongs) and 35.8mm squared for the brick outer dimensions. Here's a picture, so it's easier to understand.

[Careless]

that's a shame that they don't want to supply the schematic, but maybe they'll change their mind if we bug them.

damn, 176mm is 6mm longer than i was hoping. i wonder if there is a shorter one I can keep in the iron for storage in my carrying cases I use for my equipment. i do like the tool-less tip changing though, so i can just remove the tip I guess.

i have one coming on the way tomorrow, maybe I won't open it just yet. i was hoping i could get something to replace my ts100 that could be powered from a 100w power bank in the future for field repairs where no power is available.

thanks for measuring.

CH573DS1.PDF в конце документа нашел ссылку на сайт. Очень много информации. Будьте внимательны.
At the end of the document I found a link to the site. A lot of information. be careful )))

[Careless]

I just got the iron yesterday. It feels like a good value due to the charger and the cord and the full range of tips. the entire ensemble fits nicely in my field-repair boxes without the tip installed, but the nice tool-free gland nut is IMHO nicer than the pinecil and ts iron solutions, so I don't mind. The shell is also anodized aluminum, not plastic.

now I can leave the 19v roomba power supply and the crappy cord it has at home with the ts100. the silicone USB-C cord is super nice and flippity-floppity. the iron stays put when resting on the table without the included stand.

really hoping we can somehow get IronOS to work on this thing. It seems ok as is, but I noticed it immediately starts heating when you press the left most button and i didn't know what temp it was getting to, so i had to throttle it back.

also navigating the UI is a little cumbersome until you get used to it.

maybe I should pester them to reconsider their engineers opinion on third party firmware.

[RogWilco]

It's a pity that the schematic is the engineer's secret, he didn't share it with us, we can't help you.

This sounds more like a can't rather than a won't. Are we sure that Fnirsi is the OEM and not simply the first of many to brand a white-labelled product? I know they claim to be an OEM but it wouldn't be the first time.

I'm interested in this iron too so I'll do a little digging to see if I can find anything.

[Careless]

I emailed them as well through their website form and have not received any reply whatsoever.

In my message I didn't pressure them or anything of the sort, I just asked them to consider allowing the users of their products extend the life of their purchase by allowing themselves to offer longer term support publicly as it would be beneficial to their sales because right now TS101 and Pinecil V2 are the most popular and the HS-01 is probably not selling as well as it could because of its closed software.

maybe they got the message, maybe not. i can't tell as of yet.

I should also add that so far I'm liking the iron as is. It's a lot more comfortable to hold than the TS100 and the rubber grip stops it from rolling around on my desk... Really hoping they set this 'lil iron free.

the GVDA iron looks to be made much the same, and has a triangular shape, but the HS-01 came with everything needed for my field-repair setup.

I'm looking to buy a suitable PD65W power bank right now so I can use the iron without an outlet, and charge my usb field equipment as well.

This iron looks very promising. I love the construction.

[sasuta]

Is FNIRSI HS-01 compatible with TS100 tips

[Careless]

Is FNIRSI HS-01 compatible with TS100 tips

no. it uses it's own type of tip that i think is the same as the GVDA irons, and is supposedly just a shorter version of the T12 style tips.

[sasuta]

Thanks bro.

[Careless]

Thanks bro.

no problem.

They are referred to as "FM65"-XX tips, the XX being the same two digit identifier for the tip style as used to describe tips for the TS100 as far as I've seen.

[Ralim]

Well those usb ID's match wch-ic.com chips as expected. Good to see we have a usb bootloader there.

For next steps in IronOS at a minimum we need pinout information and general iron architecture information.
Basically this comment #1420 (comment) through to #1420 (comment) worth of information.

At the moment I dont have one of these units (or much time) to do this tracing.
If someone with the iron can do a rough pinout I can look at scheduling support.

@cvetaevvitaliy Did you disassemble your unit to take this picture? If yes would you mind describing the steps you've taken to do so? I'm trying to open mine to get the pinout and wouldn't want to break anything if possible. Thanks

[StevenSeifried]

Yesterday, I also bought a Fnirsi HS-01. For 26 EUR/~29 USD, I couldn't say "No" to it ^^
I have now also written an email to Fnirsi regarding the support of IronOS, I am waiting to see what they will answer.

[KaMyKaSii]

Kaiweets is selling the same soldering iron under the name KETS02. Maybe someone wants to try their luck regarding the scheme with them.

[Careless]

what do you mean it's quicker? at doing what, specifically?

how did you install this new firmware?

[AlexandarSteler]

It's faster-stable when making / going with temperature from scratch . It doesnt oscillate etc
Except that i downloaded from this link everything https://kaiweets.com/products/kets02

[Careless]

interesting... i didn't really see much oscilating on the FNIRSI firmware.

is the interface exactly the same as FNIRSI or are the graphics and menu different too?

[AlexandarSteler]

Everything is the same except loading name
And now I am trying in the code to change name to my name hehe .

Hi I'm new to this forum. I have a problem with my soldering iron a little off topic. As a result of the wrong voltage, the GBG3N component on the board has failed. So I bought one and when I removed the GBG3N on it and installed it on the defective one, the soldering iron started working again. I want to order GNG3N and use both of my soldering irons, but there is no component with this name on the internet. I would appreciate it if you could help what do you think this component could be or what could be used instead of it I apologize in advance for keeping the forum unnecessarily busy.

[Axweal]

Привет, я новичок на этом форуме. У меня проблема с паяльником немного не по теме. В результате неправильного напряжения вышел из строя компонент GBG3N на плате. Итак, я купил один, и когда я снял с него GBG3N и установил его на неисправный, паяльник снова заработал. Хочу заказать GNG3N и использовать оба своих паяльника, но в интернете нет компонента с таким названием. Буду признателен, если вы подскажете, что, по вашему мнению, может быть этим компонентом или что можно использовать вместо него. Заранее прошу прощения за чрезмерную загруженность форума.

"GBG3N" => "S-8261"

Fnirsi replied that they will not optimize the firmware on the HS-01 as it is not relevant. They are already developing another soldering iron. We were abandoned like puppies

[Mrcrysis555]

Hi, I’m new in this forum. I have fnirsi hs-01 When connecting the power to the adapter, there was a small short circuit, now the soldering iron does not turn on and consumes 0.012-0.020amper and a little smell of burning near type-c port and that's it all. What could have happened and how to fix it? Sorry for my off-topic question.

[bybarbaros]

Hi friends. I bought the FNIRSI HS-01 soldering iron set. I tried it for testing purposes. It worked beautifully. When I wanted to turn it on on the second day, the device did not turn on. The screen was turning on and freezing. I contacted the company I purchased it from. They somehow sent me the bios, I installed the software, but nothing changed. I contacted the company again and explained the situation. According to what they told me, my power supply was not enough. The fact that the machine I used after trusting it did not turn on the next day could not be a power supply problem. Then our correspondence continued. Finally, I tried running it with different power supplies. And finally, I made a mistake and burned the device by applying reverse current to it. I opened the device and found that the "GBG4P" integrated inside was burned. Unfortunately, I could not find this integrated device in electronics vendors in my country. My searches on the internet were fruitless. I'm waiting for your help. Thanks in advance for everything.

It should be a SOT23-6 power management ic. RY8310

[crt396]

Hello. Maybe someone can help

I recently purchased HS-01. When I first connected it (first connected it through a 5v power supply), it showed me that the voltage was low. I connected it to a 9v 2a power supply and it turned on at first and showed an icon that I needed to connect the tip, but after connecting the tip it stopped responding to any current source. Just a black screen and does not respond to any action. Please tell me what can be done and what kind of problem could be.

I look forward to hearing from you.

There is HS-02 available. https://aliexpress.com/item/1005006655028971.html Color HD OLED screen, JBC 245/210 tips can't wait writing tetris for this thing. have no idea what CPU it uses probably the same as FNIRSI HS-01 (CH571F) so it may have BLE also.

[Nickduino]

Fnirsi replied that they will not optimize the firmware on the HS-01 as it is not relevant. They are already developing another soldering iron. We were abandoned like puppies

That's a shameful behavior.

But the hardware of the HS-02 looks sweet. Color screen, three buttons, kept the cap, compatible with genuine JBC cartridges...
I don't quite get the difference between A and B, though. Are they different cartridge systems? Which is which?

[YaremchukVadym]

Greetings from Ukraine! During the first turn on with the adapter, my soldering iron burned out and smoke came out of it, then the soldering iron did not turn on, the screen did not turn on. The problem was in the inverted DC 5.5x2.1 to Type-C adapter that was included. ATTENTION, be careful! The company representative told me about it already after the breakdown, why doesn't he immediately warn and put a defective adapter? I ordered on AliExpress from the official store, so there were no problems with a free replacement, this is a big plus.

So, when I came here, after reading something, I decided to resolder the burnt microcircuit. I had a GBG4N sort of so I ordered
RY8310, I don't know if I chose correctly, because I didn't find a microcircuit exactly like mine. Next, I resoldered the chip, and wow! The screen and the soldering iron worked, but it does not gain temperature (I don’t know what to do next, and whether it is advisable... The temperature is constantly highlighted at 30 degrees and that’s it. I tried to update the firmware, it didn’t help.

Therefore, it turned out that it turned out. Maybe there will be a continuation of this topic...

[gbdlin]

I don't quite get the difference between A and B, though. Are they different cartridge systems? Which is which? https://fnirsistore.com/product/fnirsi-hs-02-smart-soldering-iron/

They are for C245 and C210 tips respectively.

[Juan-P-84]

Just joined the forum, after being a lurker for waaaay too long.
Started with the MiniWare TS80P, which I still regularly check in here to update with all the magical features being developed for it, really well done all, makes that Iron perform at its best.
Last week got my FNIRSI HS02A kit delivered, and WOW, what an amazing Iron, in combination with my ZMI Power Bank that can run it at full steam (20V, 5A, 100W)
Cant wait to see what you guys can come up with once the source code can be obtained/ deciphered, which is way above my Architectural paygrade....

All things being equal, my current impressions on the FNIRSI HS-02A outperforms and leaves my TS80P in the dust.
Heats up faster to high temps, maintains the temp better when soldering a wide gauge wire. And the TOP achievement is the C245 cartridges. When I got the TS80P I ordered it with all the available tips, and now 3 years later, there are ZERO new ones on the market. Comparatively, C245 (Clone or Original) has range of tip styles that can fill pages with product codes.

[Nickduino]

Cant wait to see what you guys can come up with once the source code can be obtained/ deciphered, which is way above my Architectural paygrade....

The source code doesn't need to be obtained. IronOS would replace the current firmware. The question is how much work would the developers need to put into adapting IronOS to yet another hardware. It does look like a great piece, I wish to see it supported one day (or an inspiration for a Pinecil V3) but that's a lot of work for very few users.

It would be really cool if the Developers do build on this platform to use IronOS, as from a hardware perspective, the HS-02 is a superior choice to much of the USB PD soldering irons out there currently. Just using C245 cartridges gives it a huge hardware upgrade path for choice of tips you want to have in your kit.

I'm happy to schedule looking into adding support if the manufacturer shares schematics.
I'll also accept a PR for support if someone wants to work on this

[StevenSeifried]

Just my 2 cents, but in my opinion, it makes sense to create a new issue for the HS-02, since it's different from HS-01.

Please don't get me wrong, I'm personally still hoping that the HS-01 gets IronOS support sometime (same for Miniware MHP50)

But spamming this issue with HS-02 stuff is needless in my opinion.

As stated earlier in this thread, the HS-01 is now outdated and replaced by the HS-02, leaving little to no hope of continuing the search for support for the HS-01. Even FNIRSI don't seem interested in the old version anymore, pushing sales on the new models.

[Nickduino]

Even FNIRSI don't seem interested in the old version anymore

Isn't that an argument in favour of an open-source firmware?

Indeed it is, but still the hurdle of getting technical information out of them.
If talk progress positively with the store rep I'm in contact with, I'll ask them about the HS-01 too.

Привет из Украины! При первом включении с помощью адаптера у меня перегорел паяльник и из него пошел дым, затем паяльник не включился, экран не включился. Проблема заключалась в инвертированном адаптере DC 5.5x2.1 к Type-C, который входил в комплект поставки. ВНИМАНИЕ, будьте осторожны! Представитель компании рассказал мне об этом уже после поломки, почему он сразу не предупредил и не поставил неисправный адаптер? Заказывал на AliExpress из официального магазина, поэтому проблем с бесплатной заменой не возникло, это большой плюс.

Итак, когда я зашел сюда, кое-что прочитав, я решил перепаять сгоревшую микросхему. У меня был что-то вроде GBG4N, поэтому я заказал RY8310, не знаю, правильно ли я выбрал, потому что я не нашел микросхемы, точно подобной моей. Затем я перепаял микросхему, и вау! Экран и паяльник заработали, но температура не повышается (я не знаю, что делать дальше, и целесообразно ли это... Температура постоянно высвечивается на уровне 30 градусов и все. Я пытался обновить прошивку, это не помогло.

Поэтому получилось то, что получилось. Возможно, будет продолжение этой темы...

В итоге удалось починить? У меня такая же проблема
