A four-channel 5 V relay shield module compatible with UNO R3 2560 boards

  • 4-channel relay shield simplifies Arduino UNO R3 2560 control projects
  • 5 V operation matches standard microcontroller logic levels directly
  • Four independent channels switch separate loads from one board
  • Shield format plugs onto UNO R3 2560 without extra wiring

4-Channel Relay Shield for UNO R3 2560

This relay shield adds four independently controlled 5 V channels to an Arduino UNO R3 2560 board. It is aimed at hobbyists and students building automation or switching projects that require multiple loads from a single microcontroller.

Expansion Board Constraints

The module draws its coil power from the host board's 5 V rail, so total switched current is limited by that supply and the onboard traces. Each channel shares a common ground with the microcontroller, preventing isolation between loads. Builders needing higher voltage isolation or more than four channels will need a different solution.

Questions about this item

Which relay shield version fits my Arduino 2560 board?

The 4 channel 5 V relay shield module is designed as an expansion board for the UNO R3 2560, so it matches that controller directly.

What does the four-channel layout mean when the shield is installed?

It provides four independent 5 V relay outputs on a single board, letting one UNO R3 2560 switch four separate circuits without extra wiring.
