This board is helpful for connecting digital systems (like a 5V microcontroller) to a high-voltage or a noisy system. This board will isolate the systems, creating a type of electrical noise barrier between devices and this board uses the TLP281 optoisolator and discrete transistors to correct the logic. This board can be used in heavy- noise environments like motor driving application to isolate the signal between the driver and the microcontroller. 

Technical Specification:

  • Maximum Voltage: 24V
  • Maximum absorption current: 500mA
  • HVCC: maximum not more than 24V
  • Size: 25mm*24mm (L*W)


  • This module isolates the low-voltage section from the high-voltage section using TLP281-4 IC
  • This IC contains 4 LEDs and four photodiodes built-in
  • 4 high-voltage channels can be controlled by microcontroller using this IC


  • Can also be used to turn on and off the servo motor and other types of motors
