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
