Enclosure for DIY LoraWan gateway for "The Things Network"

youmagine

This is a simple and compact enclosure for a DIY The Things Network gateway. Gateway For the gateway itself, you need to follow the excellent 'From zero to LoRaWAN in a weekend' and use the coredump.ch backplane. Enclosure The enclosure is easy to print, no supports needed. Note that dimensions are optimized for a 0.35mm nozzle and 2mm layer height. All parts are designed with a 0.5mm tolerance for a tight fit. The M2.5 and M3 nut slots in the base plate provide a very tight fit so that the nuts won't come out once pushed in. My enclosure is printed with Nanovia PETG-CF, but any filament should do. The case can rest on its 4 feet or be wall mounted with the adapter instead of the feet. Securing the Raspberry Pi The Raspberry Pi is fastened to the bottom plate with M2.5 screws. The coredump.ch backplane comes with 2 nylon standoffs. The easiest way is to push the nylon screws from the bottom of the case and secure the RPi by screwing the standoffs on top. For the other two points, push the nuts in the case and screw from top. Wiring The DC power is connected to the backplane either to the 5V input or the 6.7-28V input, depending on your power supply. The fan is connected to the Fan output of the backplane. I used a screw terminal instead of the header. You can then control the fan from the Raspberry Pi. BOM Aside the gateway as described in [3], you will need: 1 Panel mount DC power connector 1 5V 25x25mm fan 2 M2.5x8 screws and nuts for the Raspberry Pi (The Coredump backplane comes with 2 standoffs and screws/nuts) 3 M2.5x16 screws and nuts for the fan 4 M3x8 screws and nuts for the feet/wall mount 4 M3x8 screws with flat head for the sides (No nuts here, they are screwed in the enclosure tabs. So not over tight!) Credits The enclosure format was inspired from "The Ultimate Parametric Box". The wall mount was inspired from "Raspberry Pi 2 case with mounting bracket".
