|-
| VIN || ||Reverse-protected 2.7 V to 10.8 V motor power supply connection. Operation with VIN below 5 V slightly reduces the maximum current output.
|-
| 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.
|-
| AIN2 ||LOW ||A logic input control for motor channel A. PWM can be applied to this pin.
|-
| BIN1 ||LOW ||A logic input control for motor channel B. PWM can be applied to this pin.
|-
| BIN2 ||LOW ||A logic input control for motor channel B. PWM can be applied to this pin.
|-
| nSLEEP ||HIGH ||Sleep input: when this pin is driven low, the chip enters a low-power sleep mode. (Labeled SLP on the board silkscreen.)
|-
| nFAULT ||FLOAT ||Fault output: driven low in the event of an over-current, over-temperature, or under-voltage condition; floating otherwise. (Labeled FLT on the board silkscreen.)
|-
| AISEN || ||Current sense pin for motor A. This pin is connected to ground and does not function by default, but current limiting can be enabled by making the modifications described below.
|-
| BISEN || ||Current sense pin for motor B. This pin is connected to ground and does not function by default, but current limiting can be enabled by making the modifications described below.
