  • Using MCU embedded technology. Easy to operate, can be fine-tuned by potentiometer.003cbr003e.
  • Select the PWM signal input level range by short circuit. The module is small, easy to carry and easy to use.003cbr003e.
  • (current greater than 100mA),PWM signal receiving frequency range: 1KHZ-3KHZ.
  • When power on for the first time, it is best to do a calibration and debugging: find a signal with a 50% duty cycle and connect it to PWM and GND. Jumper caps set the corresponding voltage range. When the frequency is 1KHZ-3KHZ, use a multimeter to measure the two ports of VOUT and GND. At this time, the meter displays about 5V. Adjust the potentiometer on the board so that the multimeter displays 5.00v.003cbr003e.
