ALPS 60% keyboard PCB ===================== Primary goal is to support 60% cut AEK(Apple Extended Keyboard) layout and fits into Poker X cmpatible cases. Revisions --------- Rev.A 2015/03 Rev.B 2015/05 ISO Enter fix Rev.C 2015/10 Silk fix: position of K70, K40 and value of resistor:10K -> 1K Capslock for Cherry Stepped 1.25u Rev.D 2016/04 Fix Xtal foot print and value of R and C Rev.E 2016/08 Retouch USB connector footprint and silks Rev.F 2017/08 Add breakout for unused pins(PC4, PC6, PC7) Ideas ----- ### LED ### Backlight won't support. Indicators may be needed for debug. LED footprint for ALPS Green? ### PCB mount plate: ### 1.6mm PCB will be OK for switch plate. SMD LED? WS2812? Matias style underside LED? ### TrackPoint ### ATMega32u2 has no spare pins for TrackPoint three buttons and signals. TODO ---- Footprint library Centroid: Diode and capacitor footprint Pin1 is cathode or capacitor-positive. Pin1 is left for two pin devices like resitor and caps. Pin1 is on upper left for many pin device like DIP, QFP, SOT... http://pcbget.ru/Files/Standarts/IPC_7351.pdf http://www.screamingcircuits.com/Home/HowItWorks http://i.screamingcircuits.com/docs/understanding-the-centroid-file-r2-2.pdf Schematic: reversed pins of LED: create new LED component Silk fix: DONE 10/09 placement of K70, K40 value of resistor:10K -> 1K Capslock for Cherry Stepped 1.25u: DONE 10/09 Someone may use Cherry keycaps with stem adapters. never seen 1.25u stepped Capslock for Alps, normally 1.5u stepped or 1.75u(no stepped) for Alps ISP pads: Support for infinity bottom row: 1.5, 1, 1, 1.5: DONE 03/05 Thumb keys, split space bar: near future Trackpoint support: mount holes and IO pins: Future revision Bluetooth support: Future revision USB connector should be shifted to outside by 0.3-0.5mm. 04/05 ISO Enter Support: ISO Enter key can be used in Rev.B and later revision. The PCB supports three mount positions, 1u, 1.25u and 1.5u. See pictures and figure below. Matias has 1.25u mount, Dell and Alps have 1.5u mount and ISO Enter with 1u mount is not confirmed its existence yet. By the way, Cherry ISO key is also located in middle of 1.25u as Matias does. keycap from Matias https://geekhack.org/index.php?topic=69740.msg1760105#msg1760105 http://i.imgur.com/tiPWImU.png keycap from NEC Rakuraku keyboard(Alps) https://geekhack.org/index.php?topic=69740.msg1760805#msg1760805 http://i.imgur.com/YKIbKlrl.jpg keycap from Dell AT102W https://geekhack.org/index.php?topic=69740.msg1761095#msg1761095 https://geekhack.org/index.php?action=dlattach;topic=69740.0;attach=101849;image ------- ------- | | | | + | + | 1u | | | | ------- ------- | | | | +| | 1.25u | || | `---------' | || | | +|| | 1.5u | ||| | `-----------' .-----------, 1.5u | ||| | | ||| | ` +++ | | | | | `---------' 1.25u Support Layouts --------------- Hopefully supports AEK, KBP V60, Omnikey and Dell layouts. AEK ISO layout is not supported due to its anormaly. See below link.

Support Cases ------------- Poker X case and its compatibles. Also V60 case are supported hopefully with ballpark figure from pics.

Basicly , V60 can fit in Poker 2 case. But V60 has 6 dip switch , Poker 2 only has 4 dip switch. If the back side hole space not enough , the plate touch , not balance. Poker 2 can not fit in V60 case. Because V60 case is a little smaller than Poker 2.
