An ultra-compact dual DC motor driver built around a robust H-bridge design with 7 A continuous current per channel and a 50 A peak rating. Opto-coupler isolation on all control signals protects your microcontroller from motor-induced reverse currents, while built-in UVLO (Under-Voltage Latch-Out) and ESD protection keep your system safe.
The driver accepts 3.3 V and 5 V logic levels, making it compatible with Arduino, Raspberry Pi, and other popular development boards. PWM speed control is supported with a minimum valid pulse width of just 5 µs.
Key Features
- Dual Channel, 7 A Continuous – Drive two DC motors at up to 7 A each (50 A peak)
- Wide Voltage Range – 7–24 V DC supply (6.5–27 V absolute limit)
- Opto-Coupler Isolation – Protects control signals from motor noise and reverse current
- UVLO Protection – Under-voltage latch-out prevents erratic behaviour at low supply voltages
- ESD Protected – All interfaces include electrostatic discharge protection
- 3.3 V / 5 V Compatible – Logic high 3.0–6.5 V, logic low 0–0.8 V
- PWM Speed Control – Minimum valid pulse width of 5 µs
- Compact Size – 55 × 55 mm with M3 mounting holes

Jargon buster
Plain-language definitions for the technical terms used above.
- DC
- DC means direct current, where electricity flows in one constant direction, as supplied by batteries, USB ports and many plug-pack power supplies. When a product specifies DC, it runs from a DC supply rather than mains AC, so you need to provide the correct voltage and polarity.
- ESD protection
- ESD protection helps protect electronics from damage caused by static electricity discharges. It is useful on development boards because cables, sensors and modules are often plugged and unplugged during prototyping.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- motor driver
- An electronic circuit that lets a low-power controller switch and control a motor that needs more current than the controller pins can safely provide. Checking motor driver support matters because pumps and motors usually cannot be connected directly to a microcontroller output.
- PWM
- Pulse Width Modulation is a way for a digital pin to simulate variable output power by switching on and off very quickly. It matters for controlling things like LED brightness, motor speed, or servo-style signals from a microcontroller pin.
