Installation

There are a number of ways to interface your Raspberry Pi with the PiOT Relay board. The one you select depends on your personal preference and set-up! Each relay board is supplied with the following mounting hardware:

Ensure that your Raspberry Pi is turned off before adding or removing breakout boards

RPi 2 / 3

There are two ways to connect your B+/2/3 to the relay. You can either mount the PiOT Relay Board directly on top of the Pi using the supplied header and hardware , or by by using an IDC ribbon cable (not included). Ribbon cables can be purchase separately in a variety of colours from the ModMyPi webstore here.

Stacking on Top

Using the extra tall 40 pin header, plug the relay board to the Pi. Make sure pin 1 of the relay matches up with pin 1 of the RPi.

Connecting the relay in this manner allows multiple relays to be stacked on top of each other.

There's a trick to inserting the header into the PiOT Relay Board which is detailed in the section:

IDC Ribbon Cable Connection

Using an IDC cable, connect the relay board to the RPi 2 / 3. Making sure pin 1 of the relay board matches up with pin 1 of the RPi. You'll need a ribbon cable and a 40 Pin Header

Pin 1 and Pin 40 are labelled on the PiOT Relay Board silkscreen for reference.

RPi Zero

Solder a 40 Pin Header to the underside of the of the board

Then plug the RPi Zero directly into the board. You can use the mounting stand-off's to secure it if you wish.

Once installed, we're ready to look at the basic control operation:
