Multiple Raspberry Pi / Arduino Case

A case to hold multiple single board computers or microprocessors. Design includes mounts for PI3 & PI4 (they have the same footprint) and Arduino Mega.

Step files are included for all components.

Note - if you need access to the other ports on the PIs etc, you may have to rework the carrier / mounts / backplanes as they currently make all ports point down into the bottom of the case. I didn't need them as they're running headless as Homebridge and Homeassistant servers (powered through the GPIO header pins) with the Arduino being used as an RFLINK.

[EDIT - 18/09/2020] Added additional backplane for a Sonoff RF Bridge, and a new lid to accommodate the USB dongle Zigbee receiver I've added to my home assistant setup. The Sonoff has been flashed with Tasmota to replace the RFLINK, and the Zigbee is now controlling all of my lights, sockets and alarm sensors. Much more reliable than the old 433mhz stuff I had (and the Sonoff is only there for some RF controlled ceiling fans, an
