4 Channel Relay Module

This is a 4 channel relay module to control high power devices with low power inputs. Use a Raspberry Pi, Arduino or ESP32/8266 kit to control high voltage items like lights, pumps, or even solenoids. This board is optically isolated to protect your microcontroller from damage. Connect with the IDC connector or pin header. The IDC connector is design to work with all MudPi boards.

1x 6" IDC Cable Included
