Multiple Raspberry Pi / Arduino Case

thingiverse

A housing unit designed to accommodate multiple single-board computers or microprocessors. The design incorporates mounts for PI3 & PI4, which share the same footprint, as well as Arduino Mega. Step files are provided for each component. Note - if access to other ports on the PIs etc is required, rework of the carrier / mounts / backplanes may be necessary, as they currently direct all ports downward into the case bottom. This was not a concern since they're running headless as Homebridge and Homeassistant servers (powered through GPIO header pins) with the Arduino used as an RFLINK. [EDIT - 18/09/2020] An additional backplane has been added for a Sonoff RF Bridge, along with a new lid to accommodate a USB dongle Zigbee receiver incorporated into 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. This setup proves more reliable than the previous 433mhz equipment (the Sonoff is only used for some RF controlled ceiling fans) and outperforms the RFLINK in every way.
