You know all of those used ATmega32U4s you have laying around the workbench? That’s how this idea started – I designed a breakout board to test them. The designed for the SUPEROLED8 is based on my tool, the OLED Backpack for the USB Tester (a USB power measurement device) since it’s a proven design. Completely open source, this little board gives a hardware starting point with plenty of options. From a simple breakout board, it has turned into development board that I hope will inspire other projects.
As I work on this, I hope to improve the demo firmware, provide additional examples, finish designing the 3D printed case, and look into designing add-on boards.
