The pin names of the Fly-E3-v2
Edit me
Fly-E3-v2 Pinout Diagram
Important: The silk screen on the back of the Fly-E3-v2 has 4 errors. The EXP2 pin labeled A13 is Reset. The EXP2 pin labeled +5v is not connected. The Y driver socket STEP is PE4 and UART pin is PB6. The EXP1 pins labelled E14 and E15 are swapped. The diagrams below are correct.

Fly-E3-v2 Other Pins
If more than one pin name is availble, either name can be used in the firmware (config.g).
If the pins aren’t in the table (due to not having a special name), then the pin itself can be used in the form of PA0, PA.0, PA_0, A0, PA_0 or A_0.
