The OSMC module allows interfacing with the motors using PWM to control speed and digital logic to control direction. Two are used for each drive wheel. Essentially, the OSMC is an H-bridge motor controller with additional functionalities, such as high power operation.
Connections: 10-pin Header (logic interface)
