Dual Channel H Bridge Motor Driver Board Module - 1pc, DC5-12V, 0A-30A

Welcome to our shop! Description: This driver board is specially designed for coreless motors and is compatible with various types of motors such as toy car motors, DC motors, and electromagnetic deflection coil control. It supports forward and reverse motor control as well as PWM speed control. The upgraded product comes with a heat sink to improve reliability and a current detection circuit for a perfect PID closed-loop design. Additionally, this board has a high-speed switch with a 200kHz frequency, making it suitable for general coreless motors that require a 60kHz PWM frequency. It can withstand high current overload and has a brake function that allows for quick motor stopping. The single power source input voltage range is 3 to 15V, making it very useful for power sources less than 12V. Even with a 12V battery voltage as low as 3V, this board can still function effectively.
