Description

A truly smart relay module, offering sink and source capability (select per channel by jumper) for 4 opto-insulated inputs, I2C interface with address selection to connect up to 8 modules to the same I2C bus, and socket for WEMOS D1 mini Wi-Fi IoT module.

This 4-Channel Wi-Fi Relay module is a DIY soldering kit and comes in the size of a credit card, with just 80 x 55 mm footprint.

This DIY soldering kit offers an incredible cheap opportunity to wirelessly control 4 load circuits (up to 250VAC, 5A) from a browser interface or smartphone app – the limit is your imagination and programming skills.

The (included) D1 mini Wi-Fi module with ESP8266 can easily be programmed using Arduino IDE, and smartphone or browser apps can be developed with free and available tools like Blynk.

Turn your lights on and off, open and close your garage door, remote start your whirlpool heater and circulation pump. Whatever project comes to your mind.

CANADUINO Smarter Relays 4.2 is a Do-It-Yourself kit comprising only through-hole parts and is easy to build using basic electronic tools.

 

Substitute parts:
If we can’t source the value of the part as shown in the schematics, we will ship the kit with a substitute part close enough to guarantee proper function. Please always install the exact matching parts first, and install Substitutes at last. This way, you will not mistakenly install the wrong parts.

 

Power (5V, 500mA) can be supplied through 5V header pin or USB in case the D1 mini is installed.

    Easy to assemble, and the well documented sample program worked. I’m using this to control power to three small Cubox servers. It replaces a much larger quad 240V relay module plus custom D1 mini support board. My firmware was simple to port to the CANADUINO kit

    Love this kit. It is all-inclusive, which means everything can be housed on the single board. Yes, I could have used a wemos D1 mini + separate relay boards, but I am a fan of having everything integrated. Less “connections” mean less chance of something going awry. I used this for my home-build HVAC controller (thermostat), and it has worked flawlessly. Would not hesitate to purchase again.

    Pretty much perfect for my project. (4 channel fermentation temp controller). Showed up a day early, too!

    I bought this DIY module because I love electronics and I am very passionate about automation. It was very nice to solder the components and then program the D1 mini
    I just love to build things and this was a very pleasant project to build. It is working and there are a lot of different configurations that I can use it.
    A+
