• Low standby current, less than 0.1uA
• Built-in anti-common conduction circuit for safe operation
• Motor does not malfunction if input pins are left floating
• Low-conduction internal resistance power MOSFETs
• Simple 4-pin control interface compatible with microcontrollers
• Easy integration with Arduino, ESP32, and Raspberry Pi

Good to know

• Do not exceed the rated continuous current of 1.5A per channel for extended periods to avoid triggering thermal shutdown.
• Peak current rating is for brief bursts only; continuous operation should stay within the standard current rating.
• Ensure correct wiring of IN1-IN4 control pins for proper direction and speed control.
• Use a power supply within the 2V-10V motor voltage range matching your motor’s rated voltage.
• Avoid leaving input pins floating for extended periods; connect them to a defined logic level where possible.
• Use 100nF ceramic capacitors across motor terminals to reduce electrical noise.
• Not recommended for driving bipolar stepper motors due to the lack of built-in current limiting.
