The 2 relays on the module are independent of each other, once a relay is triggered by the low level,the corresponding LED lights will be lit and accompanied by a crisp sound. It can be controlled directly by Microcontroller(compatible with Arduino , Raspberry Pi, 8051, AVR, PIC, DSP, ARM, MSP430, TTL logic). More details can be found in: https://www.sunfounder.com/wiki/index.php?title=2_Channel_5V_Relay_Module Package include: * 1 x 2 Channel Relay Module Review: It works directly off a Raspberry PI - I spent a couple of weekends trying to get one working for the Arduino with no success, This came plugged into to Pi and heyy presto. No fiddling around nothing, works like a dream too. Review: Good dual realays for a Rasberry Pi - These have worked perfectly with a rasberry pi to make a garage door controller ## Features - 1 Year Seller warranty - Upgrade to enhance performance ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00E0NTPP4 | | Best Sellers Rank | #17,852 in Computers ( See Top 100 in Computers ) #9 in Barebone PCs | | Brand | SunFounder | | Brand Name | SunFounder | | Coil Voltage | 5 Volts (DC) | | Connector Type | Through Hole | | Connector type | Through Hole | | Contact Current Rating | 10 Amps | | Contact Material | Silver | | Contact Type | Normally Open | | Contact material | Silver | | Contact type | Normally Open | | Current Rating | 20 Milliamps | | Current rating | 20 Milliamps | | Customer Reviews | 4.6 out of 5 stars 736 Reviews | | EU Spare Part Availability Duration | 1 Years | | Included Components | 2 Channel Relay Module | | Manufacturer | SunFounder | | Maximum Switching Current | 10 Amps | | Minimum Switching Voltage | 5 Volts (DC) | | Model | 8541582329 | | Mounting Type | Surface Mount | | Mounting type | Surface Mount | | Operation Mode | Automatic | | Part Number | 2C-5V | | Specification Met | UL, CUL, TUV | | UPC | 520141421293 | ## Product Details - **Connector type:** Through Hole - **Contact material:** Silver - **Contact type:** Normally Open - **Current rating:** 20 Milliamps - **Mounting type:** Surface Mount ## Images ![(Upgraded) Channel DC 5V Relay Module with Optocoupler Low Level Trigger Expansion Board for Arduino UNO R3 MEGA 2560 1280 DSP ARM PIC AVR STM32 Raspberry Pi - Image 1](https://m.media-amazon.com/images/I/71oYyAoyO3L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ It works directly off a Raspberry PI *by D***G on 2 November 2021* I spent a couple of weekends trying to get one working for the Arduino with no success, This came plugged into to Pi and heyy presto. No fiddling around nothing, works like a dream too. ### ⭐⭐⭐⭐⭐ Good dual realays for a Rasberry Pi *by N***S on 26 June 2025* These have worked perfectly with a rasberry pi to make a garage door controller ### ⭐⭐⭐⭐⭐ Perfect for isolated control of electronics *by T***T on 28 July 2024* I am using these relays to control LED strip lighting. The controller operates on 5VDC and the lights require 12VDC. These relays provide a perfect solution. The optocouplers provide an added level of isolation. The relay coils operate on low current 5VDC. The output contacts can handle high current loads of different voltages. There is a set of NO and NC contacts for each relay. Each relay is operated independently. I recommend this product for anyone that requires isolation between the controlling circuit and the output load. ## Frequently Bought Together - SunFounder 2 Channel DC 5V Relay Module with Optocoupler Low Level Trigger Expansion Board Compatible with Arduino R3 MEGA 2560 1280 DSP ARM PIC AVR STM32 Raspberry Pi - ELEGOO 120pcs Multicolored Dupont Wire 40pin Male to Female, 40pin Male to Male, 40pin Female to Female Breadboard Jumper Ribbon Cables Kit Compatible with Arduino Projects - Arduino Uno REV3 [A000066] --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.com.br/products/276344050-upgraded-channel-dc-5v-relay-module-with-optocoupler-low-level](https://www.desertcart.com.br/products/276344050-upgraded-channel-dc-5v-relay-module-with-optocoupler-low-level) --- *Product available on Desertcart Brazil* *Store origin: BR* *Last updated: 2026-08-06*
