This motor driver module is ideal for battery-powered smart cars, toy cars, robots, and similar applications. It operates with a supply voltage range of 2V to 10V and can simultaneously drive two DC motors or one 4-wire, 2-phase stepper motor. It supports forward/reverse rotation and speed control, with a continuous current of 1.5A per channel and a peak current of up to 2.5A. The module features thermal protection and automatic recovery, ensuring safe and reliable operation.

Key Features

1. High-Efficiency Motor Driver Chip: Utilizes a professional motor driver chip with built-in low-resistance MOSFETs, generating minimal heat, eliminating the need for a heatsink, and making it compact and energy-efficient—an ideal choice for battery-powered systems. (Unlike L298N, which uses transistors, has lower efficiency, higher heat generation, and bulky design.)
2. Dual-Channel Output: Each channel supports 1.5A continuous current and up to 2.5A peak current, with built-in thermal protection to prevent damage from motor stalls, automatically recovering when the temperature decreases.
3. Compact and Lightweight: Small size and light weight (24.7×21×5mm, 5g), with no standby current, making it perfect for model cars and onboard applications.
4. Versatile Driving Capabilities: Supports driving two DC motors or one 4-wire, 2-phase stepper motor with dual H-bridge architecture.
5. Reliable Circuit Protection: Built-in anti-cross conduction circuit prevents false motor activation when input is floating. Overheat protection with hysteresis ensures safe operation even during motor stalls.
6. Wide Voltage and Current Support: Operates with a module supply voltage of 2V–10V and signal input voltage of 1.8V–7V, while maintaining ultra-low standby current (<0.1µA).

Important Notes

1. Reversing the power supply’s positive and negative terminals will damage the circuit.
2. Short circuits, output grounding, or motor stalls are protected by thermal shutdown, but prolonged operation near or above 10V voltage and peak currents exceeding 2.5A may damage the chip.
