What is it?

This is the bare board version of the DIN Rail Mount for Raspberry Pi Zero with GPIO. The first picture is the product. The other pictures show the product as components are attached. The goal was to provide a low cost, compact way to mount a Raspberry Pi Zero to a DIN clip / rail. To keep shipping costs down, the board is sent 1st class mail. The assumption is those working with DIN rails will buy a pack of DIN clips and have one ready to mount the board to. Mounting the board to the Raspberry Pi Zero can be done with 2.5mm screws. If you don't have any, you should find some in our store.

Beyond physically DIN mounting a Pi, the board has some electronic functions that can be useful: expose the 5V power input, the receive serial data, and the I2C port on screw terminal block connectors; and connect on board LEDs, push buttons, and a humidity / temperature sensor to GPIO pins. Note the temperature sensor can be heated by the heat radiating from the Pi, so it may not be a good sensor for accurate temperature measurement. The schematic is provided to make it clear how things are connected. The software used to test a populated board can be found at: https://github.com/conciseusa/SDL_Pi_HDC1000

Why did you make it?

I wanted a compact, low cost way to DIN mount a Raspberry Pi Zero, and have screw cage connectors to receive serial data from a 3.3V or 5V source, connect I2C devices and power the Pi. I added LEDs and tactile push buttons for a bit of user interface or to make it easy experiment with the GPIO pins.

What makes it special?

When shipping is factored in, it is the lowest cost DIN mount for a Raspberry Pi Zero I have found thus far.
