Build a 8A (4A per motor) dual motor driver for under $10. Introducing OctoDriver – poor man’s motor controller.
This article describes how to create an inexpensive and easy to build motor driver that can drive two DC brushed motors. The driver holds 4A per motor with 8A peak per motor. I’m including the circuit schematic and photos of a sample build on a perforated proto-board. Watch videos of motor controller in action mounted in my new wireless robot.
