## Description

ELEGOO Relay Module 4 Channel DC 5V with Optocoupler for Arduino UNO R3 MEGA Project 1280 DSP ARM PIC AVR STM32 Raspberry Pi: desertcart.co.uk: Business, Industry & Science

Review: Seems very good - Very neat little piece of kit. I'm using this module interfaced with IR detectors for train detection on hidden model railway storage loops. The IR detectors have an output which goes low when an object is detected and this module requires an input which goes low to activate the relay, so they work together a treat, all running off 4.5 - 5V. Also comes with a tiny screwdriver for the terminals and a ribbon cable for connecting up - very useful! I can't comment on the life expectancy of the relays though.
Review: Well made and works perfectly - Compact, easy to use, well laid out and fair value for money.

## Features

- 5V Active Low Operation: This relay module operates at 5V and should not be powered by 3.3V, as it may not drive the relays effectively. Ensure the power supply current exceeds 1A for reliable performance.
- High Current Handling: Each relay can handle maximum contact ratings of AC250V 10A and DC30V 10A, making it suitable for controlling various appliances and devices requiring high current. Working status indicator lights are conducive for the safety use
- Standard Microcontroller Interface: Features a standard interface for direct connections with microcontrollers such as Arduino IDE, Raspberry Pi, STM32, AVR, PIC, and ARM, allowing for easy integration into projects.
- GPIO Low-Level Logic Control: This 4-channel relay module utilizes low-level logic voltage to drive the relays, which reduces power consumption and protects the control board from damage. This allows ESP32 and Raspberry Pi GPIOs to directly control the relays without the need for external transistors or logic-level converters.
- Applications: Widely used for all MCU control, industrial sector, PLC control, smart home control.

### ⭐⭐⭐⭐⭐ Well made and works perfectly
*by D***D on 21 November 2023*

Compact, easy to use, well laid out and fair value for money.

### ⭐⭐⭐⭐ Reliable, but the relays are poor quality - switch them out for Omron
*by A***S on 28 February 2020*

Like others the board is very good, but the relays have a tendancy to latch in a closed state if they have been energised for a period of time. I switched out the relays for OMRON G5LA-14-5VDC - you can't buy them here anymore as OMRON have discontinued them, but ebay has plenty of listings still from China (i used the seller smallpartsbigdifference) and they have been rock solid since.
