Summary
Dual H-bridge motor driver module. Controls the direction and speed of two DC motors, or one stepper motor, from logic-level signals — the go-to cheap driver for beginner robotics and RC car builds.
- Motor supply voltage: 5V - 35V
- Logic supply: 5V (onboard regulator, or external)
- Max output current: ~2A per channel (with heatsink)
- Channels: Dual H-bridge (2 DC motors or 1 stepper)
