Digispark HAT for M5StickC

thingiverse

This prototype connects DigiSpark or compatible boards to M5StickC. It was created with reference to the following site, Lang-Ship. The specific project is "Trial of USB keyboard function with M5StickC and DigiSpark(ATTiny85)" by @tnkmasayuki, located at https://lang-ship.com/blog/?p=1219. Special thanks go to Tanaka Masayuki for sharing the details. CAD files are available for this project, including at85-c_27.stp in STEP format and STL files at85-c_27_top.stl and at85-c_27_btm.stl. To create this prototype, you will need: * Digispark or compatible boards * A square piece of universal board with 8x9 holes, measuring 21x23mm and 1.6mm thick * 2.54mm pin header connectors * Right angle 2.54mm pin headers * Jumper Header (optional) Please refer to the above site and photos for instructions on how to make this prototype. To connect M5StickC and DigiSpark, follow these steps: * Connect GND to GND * Connect SDA on GPIO 0 to P0 * Connect SCK on GPIO26 to P2 Optional: If you want to add a jumper Header and 2.54mm pin header connector (3pin), you can do so. The wiring is as follows: 1. NC (no connection) 2. DigiSpark[5V_out] 3. M5Stick [5V_in]
