## Description

Quickly control 3- or 4-wire sensorless brushless motors without additional components, 7-12VDC power supply for speed adjustment via potentiometer and speed increase with voltage. The direction of rotation is simply selected CW or CCW via jumper, and the board includes reverse polarity, overcurrent and short circuit protection for safe use in projects.
Driver module for brushless motors, with 3 or 4 wires, which does not require additional components to work. Compatible motors are those with voltages between 7 and 12VDC. The higher the voltage used, the higher the engine speed.
On the board there is a rotation selector, with a jumper, for CW (clockwise) and CCW (counter-clockwise).
The motor speed is controlled from the potentiometer on the pad.
The board has polarity protection, over-current protection and short-circuit protection.
Locating the common port (COM) of the 4-wire motor:
To determine which wire of the motor is the common one (COM), all 4 terminals will be measured with a multimeter set to the resistance check. The one with the lowest resistance connected to the other 3 wires is COM.
