Featuring selectable high/low level triggers, optocoupler isolation for enhanced safety, and clear LED status indicators, these relays handle up to 10A at 250V AC or 30V DC, making them ideal for reliable automation in DIY and professional projects. ## Description This is 3 pieces of 5V 1-channel relay modules that work with Arduino, ESP32, ESP8266, Raspberry Pi, or any 5V or 3.3V microcontroller. A single package includes 3 pieces of relay modules. SPECIFICATION: - Normally open and normally closed. - High-level trigger or low-Level trigger selection by a jumper. - Optocoupler isolation. - Terminal blocks for both input and output. - Two LED indicators: power (green LED), the relay status (red LED). - Fault-tolerant design, even if the control line is broken, the relay will not operate. - Operating voltage (power): 5V. - Trigger voltage: 3.3V to 5V. - Trigger current: 5mA. - Maximum load: AC 250V/10A, DC 30V/10A - Dimension: 50mm x 26mm x 18.5mm (L x W x H). INPUT INTERFACE: - DC+ : Connect the positive pole of the 5V power supply. - DC- : Connected the negative pole of the 5V power supply. - IN: Signal trigger input (3.3V to 5V, high or low level signal selected via a jumper). OUTPUT INTERFACE: - NO: The normally open interface. - NC: The normally closed interface. - COM: The common interface for both normally open and normally closed. High/low level trigger selection jumper: - If the jumper is placed between COM and L, the relay uses LOW level trigger. - If the jumper is placed between COM and H, the relay uses HIGH level trigger. HOW IT WORKS: High Level Trigger: - When IN is LOW level signal, the NO does not connect with COM and the NC connects with COM. - When IN is HIGH level signal, the NO connects with COM and the NC does not connect with COM. Low Level Trigger: - When IN is LOW level signal, the NO connects with COM and the NC does not connect with COM. - When IN is HIGH level signal, the NO does not connect with COM and the NC connects with COM. TUTORIALS: - Arduino and ESP32 online tutorials: DIYables Relay Review: For three relays at this price? No brainer. - These 5V 1-channel relays have been exactly what I needed. The 3-pack gives you flexibility across multiple projects without breaking the bank. Wide compatibility!! works with Arduino, ESP32, ESP8266, Raspberry Pi, or any 5V/3.3V microcontroller. Trigger voltage range is 3.3V to 5V, so no level shifting headaches. Versatile switching: has both normally open (NO) and normally closed (NC) contacts, plus the ability to select either high-level or low-level trigger via a simple jumper. Rare to find both options on budget relays. Built-in protection: optocoupler isolation keeps your microcontroller safe when switching higher voltages. The fault-tolerant design is a nice touch too: even if the control line breaks, the relay won't accidentally activate. Solid specs: handles up to 250V AC / 10A or 30V DC / 10A. More than enough for lights, fans, and most household stuff. For three relays at this price? No brainer.

I used this to control a little door strike from esp32 via home assistant. Once you understand how to wire for open and not open options, with common, it's not too tricky and works well. I liked I got 3 incase i messed up one, or needed multiple relaying. The terminals that screw down are a plus for quick connecting and disconnecting ## Frequently Bought Together - DIYables 3pcs Relay Module for Arduino, ESP32, ESP8266, Raspberry Pi, 1 Channel, 5V, High/Low Level Trigger - TMEZON 12 Volt 2A Power Adapter Supply AC to DC 2.1mm X 5.5mm Plug 12v 2 Amp Wall Plug Extra Long 8 Foot Cord LED Strip Module Light - DIYables DC Power Jack Plug Adapter Connector for LED Strip, DC Motor, Stepper Motor, CCTV Camera, 2.1 x 5.5mm Male Female 5 Pairs --- ## 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.id/products/472780685-3pcs-relay-module-for-arduino-esp32-esp8266-raspberry-pi-1](https://www.desertcart.id/products/472780685-3pcs-relay-module-for-arduino-esp32-esp8266-raspberry-pi-1) --- *Product available on Desertcart Indonesia* *Store origin: ID* *Last updated: 2026-07-27*
