Overview

Motor and solenoid control on one board

A board-level module combining bidirectional DC motor drive, using an H-bridge topology, with solenoid switching — for OEM embedded builds.

Motor enable, forward / reverse, and solenoid on / off are driven by 3.3 VDC control signals, and an open-collector encoder input provides motion feedback. Motor and solenoid supplies are individually fused.
