VMM | This pin gives access to the motor power supply after the reverse-voltage protection MOSFET (see the board schematic below). It can be used to supply reverse-protected power to other components in the system. It is generally intended as an output, but it can also be used to supply board power. | |
GND | Ground connection points for the motor power supply and control ground reference. The control source and the motor driver must share a common ground. | |
AOUT1 | The motor A half-bridge 1 output. | |
AOUT2 | The motor A half-bridge 2 output. | |
BOUT1 | The motor B half-bridge 1 output. | |
BOUT2 | The motor B half-bridge 2 output. | |
AIN1 | LOW | A logic input control for motor channel A. PWM can be applied to this pin. |
