About the Wood cube PCB
Wood cube is an open source PCB design by CUBE-SD-Project, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 50.5 × 50.5 mm, with 24 components from 16 distinct parts.
Other key parts include the WeMos_LoLin32_Lite. By type, the board carries 7 resistors, 6 switches, 4 connectors, 3 capacitors, 2 ICs and 1 battery holder.
From the project
Early Curiosity - Cube
This is the documentation for the third version of the cube. v1 is available here and v2 here. Pictures of the development are available online(v2 here).
The cube has a button on five of its faces, and a hatch on the bottom face. Under the hatch, there is: - A USB-C port for programming and battery charging. > [!IMPORTANT] > To charge the battery, the cube needs to be on. - A switch to turn the cube on and off. - A micro-SD reader.
