Code Issues Releases Wiki Activity

Parametric potentiometers added, changes PCB "potentiometer" parameters.

Browse Source 
The first one is now the type that defaults to the previous BigTreeTech version.
The second parameter is the shaft length overrride.

Added ESP32_DOIT_V1, ArduinoNano and KY_040 breakout PCBs.
