Description:
This controller board is specially designed for coreless motors and will work very well with coreless motors. It is compatible with reverse motor control and PWM speed control. This board uses MOSFET with extremely low internal resistance, with dead band control that minimizes the losses of the MOSFET switch and improves the utilization rate of the power supply. The MOSFET controller chip has built-in hardware brake function and power feedback function. It is a good choice for ordinary DC motors and coreless motors etc.
