Updated: 25/8/2021

SKU: MODULE-006 Categories: , Tags: ,


This design uses the optoisolator to detect the mains electricity. It allows a microcontroller to get information about whether 110/220VAC voltage appears.


  • Logic voltage 1.8V, 3.3V, 5.0V
  • 110/220VAC detection
  • LEDs indication

Product includes professional library, confirmed schematic design. Our design has also a full output job and active Bill of Materials.
