Feature

●【PID Design】: The improved product comes with a heat sink to improve reliability and current detection circuit to realize a perfect PID closed loop design. This driver card is specially designed for the coreless motor and works great with coreless motors
●Switch design: this board has a high-speed switch. General coreless motors require 60KHz PWM frequency and this board is equipped with a 200kHz switch. MOSFET driver chip has built-in hardware braking function and energy feedback function
●【High Power Efficiency】: This board can withstand high current overloads and has a braking function that can quickly stop the motor. This board uses a MOSFET with extremely low internal resistance, with dead band control, which minimizes MOSFET switching losses and improves the utilization rate of the power supply
●Working voltage: the input voltage of the individual voltage sources of this board is 3 to 15 V. If you use a power source with less than 12 V, this board is very useful. It can still work, even the voltage of a 12V battery is as low as 3V. It is a good choice for ordinary DC motor and coreless motor etc
●【Application】: Can be used for all kinds of toy car motors, semiconductor cooling control, DC motors, electromagnetic deflection coil control. It supports forward and reverse motor control and PWM speed control
