Raspberry Pi and 2-Channel-Relay Case

Raspberry Pi 4 & 2 Channel Relay Module Case

This snug enclosure is designed to host a 2 channel relay and a Raspberry Pi 4. It is assembled with only two head socket screws. There is room for short jumper cables (female-female) and the DC cables running IN and OUT (1 and 2). The Raspberry Pi is powered by USB (Pi). It is recommended to zip tie the cables on the inside for strain relief. The camera ribbon exits through the ventilation slots.

This combination of Pi and relay is intended to be used with Octoprint and two lights (main and fill light). I use the enclosure plugin to control the Pi's GPIOs.
