Description
Simplified DigiSpark :
- external power removed
- only keep 1 external pin
Main use to trigger USB HID Keyboard string or characters with 1 external button.
I cloned the https://oshwlab.com/ismaileren.akkus67/attiny85-devboard project to get the USB A male layout on the PCB. Be careful, everything else is changed (components as well) !
