I've had this idea in mind for a while and the Hackaday Business Card Contest is the perfect motivation to bring this idea to life. I'm in a frantic scramble to finish the design and get a board running before the close of the contest!
Features:
Built-in schematic with illustrated test points
Built-in motor with option to connect external motor and hall sensors
Adjustable winding configurations via solder jumpers
ATmega328PB - Arduino compatible (via USB-FTDI cable)
Capacitive touch buttons (Mode, -, +, Select)
RGB User LED
SAO port for an SAO OLED, of course!
