Hilitand DC 5 12V Motor Controller Dual channel H bridge Motor, Driver Board Module 0A 30A with Heat Sink

HEAT SINK EQUIPPED: Upgraded product comes with heat sink to improve the reliability and current detection circuit to realize a perfect PID closed-loop design. SPEED SWITCH: This board has a high speed switch. General coreless motors need 60kHz PWM frequency and this board is designed with a 200kHz switch. WIDELY USED: This motor controller suit for all kinds of toy car motors, semi-conductor refrigeration control, DC motors, electromagnetic deflection coil control. CAN STAND HIGH CURRENT: This motor control board can withstand high current overload and has brake function which can stop motor quickly. WIDE INPUT VOLTAGE: Single power source input voltage range of this board is 3V 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.
