This parts adapt a LED matrix to the UC2 cubes. Electric control is done by an ESP32.
To acquire the STL-files use the UC2-Configurator. The files themselves are in the RAW folder. The module can be built using injection-moulded (IM) or 3D-printed (3DP) cubes.
It can be used for Fourier Ptychographic Microscopy (FPM, Horstmeyer 2014), quantitative differential phase-contrast (qDPC, Tian&Waller 2015) or oblique illumination, etc.
The basic properties/features of the assembly go here.
- No support needed in all designs
- Carefully remove all support structures (if applicable)
The Cube consists of the following components.
- The LED-Matrix Adapter which adapts to the Neopixel LED Matrix display. (UC2_30_IM_LED_holder_v3.stl)
- Check out the RESOURCES for more information!
- 2× M2 screws with nuts for connecting the LED matrix to the adapter, alternatively use hot glue
- 1× ESP32 🢂
- 1× LED-Array, 4×4 🢂
- 3× Female-Female Jumper Wire, 0.14 mm² 🢂
- 1× Power cable for ESP32 - USB-microUSB 🢂

The assembly of this part is straight forward. Just solder the wires to the matrix and connect it to the plate that adapts it to the cubes.
The DIN, 5V and Gnd-Pin have to be connected to the ESP32. The ESP32 connects to the supply voltage (5V).
- All parts for this model
- Solder the 3xpinhead to the LED-Matrix. Cover the exposed wires with electrical tape to avoid short cicuit.
- Place the LED matrix on the holder. The little slot is for the wires.
- Using the two M2 screws, attach the matrix to the holder
- Fix the screws with nut. Connect the electronics - Done!
Don't burn yourself if you solder the part!
- Open Electronic Contacts can deduce a shortcut!
