170W H-Bridge NMOS Motor Driver Module PWM Speed Controller DC
170W H-Bridge NMOS Motor Driver Module PWM Speed Controller DC
170W High Power H-Bridge Motor Driver Module – NMOS PWM Speed Controller
Take full control of your DC motor projects with this 170W H-Bridge Motor Driver Module. Built around a dedicated full-bridge driver IC paired with four external low-resistance NMOS transistors, this compact board delivers high-current performance with minimal heat generation — making it ideal for robotics, DIY automation, CNC systems, and maker electronics projects.
Made in Mainland China.
Key Features
- High-Power NMOS Design: Uses a full-bridge drive chip plus four 55V / 110A low internal-resistance NMOS transistors for efficient, high-current motor control up to 170W.
- Forward, Reverse & Instant Braking: Supports full bi-directional motor rotation and instant braking with just 3 input signal lines.
- Dual PWM Inputs: Adjustable duty cycle from 0–100% for precise, smooth motor speed control.
- Wide Operating Voltage: Compatible with 10V–40V power supplies (optimized for DC 5–30V logic environments), handling loads below 170W.
- Universal Logic Level Support: Works with both 5V and 3.3V logic signals — directly compatible with Arduino, Raspberry Pi, STM32, ESP32, and virtually any microcontroller I/O port.
- Built-In Dead-Zone Hardware Control: Onboard dead-zone management reduces switching losses and protects NMOS transistors during frequent direction reversals.
- Tinned PCB Traces: The rear of the module features tinned copper pads for enhanced current-carrying capacity and reliable soldered wire connections.
- Analog Input Support: Motor direction and speed can also be controlled via analog voltage inputs for versatile integration.

Frequently Asked Questions
Q: What microcontrollers are compatible with this H-Bridge motor driver module?
A: This motor driver module supports both 3.3V and 5V logic levels, making it directly compatible with a wide range of microcontrollers including Arduino (Uno, Mega, Nano), Raspberry Pi, STM32, ESP32, ESP8266, and virtually any standard single-chip MCU I/O port — no level shifter required.
Q: Can this module control motor speed and direction simultaneously?
A: Yes. The dual PWM input design allows you to adjust motor speed (via 0–100% duty cycle) and direction (forward/reverse) using just 3 control signal lines. Instant braking is also supported, making it ideal for applications that require frequent or rapid direction changes.
Q: What is the maximum motor power this driver module can handle?
A: This module is rated for DC motors up to 170W with an operating voltage range of 10V to 40V. The four external 55V / 110A low-resistance NMOS transistors ensure high current throughput with minimal heat buildup, and the tinned PCB rear pads further support robust, high-current wire connections.
