The mLink relay modules are a range of 5V relay modules that have been designed to be controlled either manually or via a microcontroller. For manual control there is a set of digital pin(s) that can be toggled to directly control the relay. For controlling via a microcontroller there is a serial I2C interface minimising the amount of pins required to control multiple relays or relay modules.

For Arduino users you can use the mLink library (see below) to control any type of mLink module. Only one single instance of the library is needed to control multiple types of mLink modules resulting in very little resources overhead and therefore making it great for Arduinos with small amounts of memory and pin counts.

Thomas X. ★★★★★

The manual pin toggle works flawlessly for quick switching, and the 5V logic level is clean enough to drive straight from an Arduino without extra circuitry. I've had it running for a week straight and not a single hiccup.

Joshua ★★★★★

Setting up the manual digital pin control was a breeze, and the board responded instantly when I toggled it with my Arduino. It’s a solid little 5V module that does exactly what it says, and the screw terminals make wiring up loads secure.

Scarlett Q. ★★★★★

Using the I2C interface to control multiple relays from my Arduino freed up GPIO pins I desperately needed for sensors. It responds instantly to commands
