  • I think in the I2C example you need to add 10k pullups on the SDA and SCL on both sides of the level shifter as I2C is O/C

  • Be aware I just fried this board and my MCU (a Teensy++) by turning on the motor voltage VM (12v) first before turning on the 5v Vcc. It had been working great for weeks before that. I’m not sure why this would cause it to burn out as the VM seems to be isolated from the Vcc, and STBY would be low if there was no Vcc, so everything should be disabled. But anyway be safe and connect Vcc before the motor supply VM.

No public wish lists :(
