Laser Printers By LiebeWH

• Upgraded product comes with heat sink to improve reliability and current sensing circuit to achieve a perfect PID closed-loop design
• Suitable for all kinds of toy car engines, semiconductor cooling control, DC motors, electromagnetic deflection coil control
• This board has a high speed switch. Coreless motors in general need PWM frequency of 60kHz and this board is designed with a 200kHz switch
• This plate can withstand high current overload and has brake function that can stop the engine quickly
• The input voltage range of the single power supply of this board is 3-15V, if you use a power supply less than 12V, this board is very useful. It can still work even if the voltage of a 12V battery is as low as 3V
