This dual-channel H-bridge driver runs two brushed DC motors independently, each in either direction, from a 5 V to 30 V supply at up to 10 A continuous per channel. It is the two-channel version of Cytron's MD10C.
Both bridges are fully NMOS and need no heatsink, and the continuous rating was tested at 25 °C. Switching is solid-state, so it responds faster than a mechanical relay and has no contacts to wear out.
Each motor takes two signals from your controller, PWM for speed and DIR for direction, on a single 5-pin header with a shared GND. The inputs accept 3.3 V and 5 V logic, so it works with 3.3 V and 5 V boards such as Arduino, Raspberry Pi, Raspberry Pi Pico and ESP32. Cytron publishes an Arduino library with examples, plus tutorials for getting started.
The motor supply has no reverse polarity protection, so check polarity before powering up. The PWM inputs need a TTL signal from a microcontroller, not RC PWM from a receiver. For inductive loads, power it from a battery: regenerative current can shut down a switching power supply. If you must use one, put a battery of the same rated voltage in parallel to absorb that current.
Features
Check your wiring before writing any code: two test buttons per channel drive each motor in each direction without a microcontroller.
See what each motor is doing: a red LED for each output direction (M1A, M1B, M2A, M2B), plus a green power LED.
Speed control up to 20 kHz: the output PWM frequency matches the input.
Controlled stopping: regenerative braking, and both outputs of a channel pull low (brake) whenever its PWM input is low.
Speed and direction from one PWM line: in locked-antiphase mode, 50 % duty stops the motor and the duty cycle above or below 50 % sets direction. Sign-magnitude PWM is also supported.
Handles short surges: up to 30 A peak per channel for up to 10 s.
One supply to wire: the logic runs from the motor supply, so there is no separate logic supply to provide.
Ready to wire: the supply and both motors connect to pre-soldered screw terminals.
