These are awesome for the Arduino or Raspberry Pi, you can directly drive them from the IO pins with no additional hardware! This relay board will allow you to directly control 4 individual channels at up to 10A 250 or 120VAC, or 10A at 0-30V DC. They’ll require 5V power from the board you’re using to control them, otherwise the IO pin connects directly to the headers on this board. An onboard opto-isolator and transistor will keep your microcontroller safe.
