Description
Dual-channel H-bridge driver working mode creates higher working efficiency. Large capacity filter capacitance, afterflow protection diode, more stable and reliable..Upgraded product comes with heat sink to improve the reliability and current detection circuit to realize a perfect PID closed-loop design..This board has a high speed switch. General coreless motors need 60kHz PWM frequency and this board is designed with a 200kHz switch..Suitable for all kinds of toy car motors, semi-conductor refrigeration control, DC motors, electromagnetic deflection coil control..This board can withstand high current overload and has brake function which can stop motor quickly. Single power source input voltage range of this board is 3 to 15V, if you use a power source less than 12V, this board is very useful. It can still work even the voltage of a 12V battery is as low as 3V.
