Will a Bigtreetech EZ2209 driver w/pin out board be a direct replacement for the TMC2209 driver on a SKR Pro 1.2?
It should work, but I have heard reports that the sensorless homing won’t work because the connector board doesn’t have it in the right spot. I don’t think anyone uses sensorless homing on CNC machines so this probably won’t matter.

Back when my big LowRider was still version 2, I did indeed use sensorless homing with my TMC 2209 drivers. However when I updated to version 3 I switched to the endstop switches.
