4-Channel Relay HAT Module Board for Raspberry Pi4B, Pi 3B/3B+

  This Raspberry Pi HAT gives you the ability to control four high voltage/high current devices through relays. It can be used to make normal home appliances become intelligent. The HAT should be connected to the RPi using the 40-pin female header. You can stack up to 4 relay modules on one RPi unit in order to control more than 4 channels. The I2C address of each HAT can be changed using the on-board DIP switch.

Remarks:

  • The 4 pin header is a backup that supplies power to future products. You can ignore those pins. Please DO NOT connect any devices to those pins.
  • In order to have a complete understanding of how this module works, PLEASE consult the user manual in the attachment section.
