  • The board has pins for powering the motors externally, but the hookup guide says that the DRV8835 H-bridge is hard wired to 5V. Do I need to disconnect the 5V hard wiring somehow before using the external power pins?
    I am using a pair of L-shaped TT motors and encoders and at only 3 Ohms of resistance I find that the motor needs to draw 1.7A to start from stall when powered with 5V. If I can power the H-bridge with only 3.3V then the current draw should remain below the 1.5A max and 1.2A steady state limit.

No public wish lists :(
