v1.x Pinout
v2.x Pinout
Notes:
- To enable UART communication, the jumper on the driver has to be bridged from the middle to the respective position.
- TMC2208 drivers are in stealthChop mode by default.
- TriGorilla boards set the configuration pins
MS1+MS2+MS3to 5V (high), which will set the TMC2208 into 1/16 stealthChop mode.
