10pcs DIY LM358 DC Motor Speed Controller Kit DC Motor Speed Module Kit
This module uses PWM (pulse width modulation) to control the speed of the motor, adjust the duty cycle of pulse width to make the speed change from 0 to maximum. The wider the width of control waveform peak, the faster the motor speed; conversely, the wider the width of control waveform trough, the slower the motor speed. High-quality devices are used in circuit boards and components to ensure the success rate of fabrication and circuit stability.
PCB size: 4.7 x 3.4 mm.
Working voltage: DC5.5V – 12V.
Maximum current: There is no test at present, estimated at about 2A. Buyers are requested to add heat sinks to TIP41 transistor for high current.
Speed range: adjust < – > full speed.
