This is a small case for a LoRaWAN Gateway using a Raspberry Pi Zero W and a WM1302 LoRa gateway module from Seeed Studio. The case exposes only the MicroUSB connector for power supply and an SMA connector for the LoRa antenna to minimize its size. The WM1302 gateway HAT's GPS antenna is mounted in the case's lid.
It is made of three main parts:
- A base which holds the Raspberry Pi Zero W and an SMA connector
- A middle part, which holds the WM1302 gateway HAT and is stacked on top of the base
- A lid, which has a snap-in cut-out for the GPS antenna, with an optional clip to fix the antenna in the lid.
All three parts are screwed together from the top with two M3×20 screws, which go into two threaded inserts in the base part.
BOM
To build the case and add all electronics as seen on the photos, you will need:
- Raspberry Pi Zero W with Pin Headers, MicroSD Card
- Seeed Studio WM1302 LoRaWAN Gateway
- WM1302 LoRaWAN Gateway Module SPI (make sure to the the SPI version, the case does not have space for the USB connector and you cannot connect it to the Pi Zero, also check the region, link points to EU868)
- WM1302 LoRaWAN Gateway HAT
- Micro USB power supply
- u.fl to SMA pigtail to make the antenna port available on the outside
- Antenna
- 2×M3 screw 20mm
- 2×M3 threaded insert (e.g. from Ruthex)
Print Settings
- PETG recommended
- I used a 0.6 mm nozzle and 0.3 mm layer height for printing, 0.4mm nozzle and 0.2mm layer height should work fine as well
- no supports needed (print the lid on its back)
