Overview

The Arduino Nano Every relay shield provides flexibility for you projects. It can be used with both the Arduino Nano and the Arduino Nano Every microcontroller board. There are two individually controllable relays on board. The relays are optocoupler isolated from the Arduino microcontroller. Screw terminals are used to break out the output pins from the relays.

Male pin headers are used to breakout all the I/O, I2C, serial, as well as power and ground. There is a 6 position connector that can be used to expand the relay control capability of the board or it can be used for general I/O. The connector has power, ground, and 4 digital pins routed to it. These four pins can be isolated through the corresponding DIP switch.

This relay shield comes fully assembled except for the female headers for the microcontroller. This is because the Nano Every has castellated holes and no components on the bottom side. Therefore it can be soldered directly to the board for a permanent solution. The female headers are included if you want the capability of easy prototyping or swapping between controllers.

The screw terminals may come in green or blue.
