“Works for me BUT DO NOT use a Grove connector as the polarity is reversed ... look at the wiring diagrams on their wiki before adding to your circuit. Thankfully they include a cable that is wired correctly - no idea why they didn't stick to the grove pinout (seems none of their items with a grove connector conforms). The config switch makes it a bit bulky but works easier than bridging contacts.
Currently it's in an OnStep controller using a Fysetc S6 board (onboard EEPROM corrupts the I2C bus).”
