3pcs DIY LM358 DC Motor Speed Controller Kit DC Motor Speed Module Kit

Description: 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. Package Included: 3 x DIY LM358 DC Motor Speed Controller Kit
