## Description

ELEGOO Relay Module 4 Channel DC 5V with Optocoupler for Arduino Projects | Compatible with UNO R3 MEGA1280 DSP ARM PIC AVR STM32 Raspberry Pi: desertcart.co.uk: Business, Industry & Science

Review: Solidly built module - This is a solidly built module, well constructed, great soldering and very nicely finished. I feel it inspiring enough to buy another when I need as, although I could make my own, it wouldn't be as good and would be for no real financial saving either. It's being used as a mute function within balanced line studio desk audio outs. Thank you.
Review: Does what it says and good value - Easy to control and does exactly what I wanted it to do - control a 12v pump and double water/Solenoid Valve for an irrigation system

## Features

- 5 V Active Low Operation: This relay module operates at 5 V and should not be powered by 3.3 V, as it may not drive the relays effectively. Ensure the power supply current exceeds 1 A for reliable performance.
- High Current Handling: Each relay can handle maximum contact ratings of AC 250 V 10 A and DC 30 V 10 A, making it suitable for controlling various appliances and devices requiring high current. Working status indicator lights are conducive for the safety use.
- Standard Interface: Features a standard interface for direct connections with microcontrollers — compatible with Arduino, 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, the industrial sector, PLC control, and smart home control.
