The module outputs PWM signal by NE555 circuit to control the speed of DC motor. D1 is used to prevent NE555 circuit from damage of the reversely connected power. D2, C1, R1, R2, W1, IC1 are combined to be width adjustable pulse generator. Adjust potentiometer W1 can change pulse frequency and pulse width output by IC1NE555. The output pulse adjusts the motor speed when it passes drives R3, R4, R5, Q1 and Q2. D3 and D5 eliminate the counter electromotive force generated by the motor to protect the transistor Q3. C2 and C4 are power filters. C3 is stable reference voltage to eliminate interference.
