Review: Pairs nicely with an arduino or other microprocessor - It's well thought out. It's easy to control the relay from a low power processor pin - just a couple mA will do the job. You can select whether the relay is triggered by a Vcc or ground signal, and the relay itself is SPDT. It works fine at 5v. The board has a power LED, which is annoying because power drain is an issue with battery circuits, and a separate LED which lights when the relay is energized, which is more acceptable. They can be removed. The relay itself is small and won't switch high currents at high voltages, but you can easily use it to control small lights, little motors or a larger relay. Pleased.
Review: Versatile little 5V Relay board. - Well documented above, rare for such DIY parts. No soldering required (for those who don't like that). Very versatile, you can reverse the input logic with the jumper. I also like that the output terminal provide both NO (Normally Open) and NC (Normally closed) so it can adapt to your application when you lose power to the boards with NO or NC. I find the green power LED very bright. I might remove it from the board. The red LED is just bright enough in my opinion. Very well packaged, individually wrapped, they look like candies! Works well driving and powering the relay with a Wemos D1 mini with the D6 pin (digital 6). I have flashed the Wemos with Tasmota. WOULD BE A KILLER BOARD IF: it was combined with a transformer and regulator so it could produce 5V from the OUTPUT lines. I mean I'm mostly driving 120V on the relay output side. If the board could take Line+Neutral, then you could power the relay board and the Wemos micro without an external power supply. Essentially, creating a smaller Sonoff. Martin Politick January 2020.

## Features

- 【Control Devices】The 1-channel relay module uses genuine high quality DC5V relay and SMD opto-isolator supporting high/low level trigger, widely apply to control various AC/DC appliances, and other devices with large current.
- 【Load Range】NO(Normally open) maximum load < AC 250V/10A, < DC 30V/10A. Trigger current of opto-isolator: 5mA.
- 【Fault-tolerant Design】The relay will not operate even if the control line is disconnected.
- 【Universal Interface】Equipped with screwed terminal plate and fixed bolt holes(diameter: 3.1 mm) on both sides for easy installation.
- 【High Compatibility】The relay module can be controlled directly by 5V logic signals from microcontroller(8051, AVR, PIC, DSP, ARM, Raspberry Pi, MSP430, TTL logic etc)

### ⭐⭐⭐⭐⭐ 3.3/5v capable, fast, smooth, and cool!
*by A***6 on January 6, 2021*

Fantastic set of 5v relays for the price. Warmth is very manageable. I’ve ran 110v through one for a dehumidifier that basically ran 20 hours a day for a month and was safe to hold my hand for as long as I wanted on it. Been moving more and more to esp devices. And with a recent home assistant setup I have gone nuts with esps. These 5v relays work fantastic and reliable at 3.3 volts as well!
