Since I live in an area that was without LoRaWan TTN coverage, I needed to build my own gateway. I decided to go for the proven combination of IMST iC880A LoRaWan Concentrator + Raspberry Pi 2. Just for fun I 3d-printed a mounting base for the two boards in a neat Aluminium case.
Building the gateway is pretty easy. I’ll post more details shortly.
Bill of Materials
|Part||Where to get it||Price in CHF (approx.)|
|Raspberry Pi 2 with 8GB Micro SD Card||Digitec|
Micro SD card sold separately, don't forget to order!
|IMST iC880A-SPI – LoRaWAN Concentrator 868MHz||IMST Webshop||200.--|
|Aluminium case 165 x 110 x 55 mm||Conrad||20.--|
|Mounting base for Raspberry Pi and LoRaWan concentrator||CAD file for 3D printing|
Use PLA, not ABS
|Low power connector Socket, vertical vertical 5.5 mm 2.1 mm||Conrad||6.--|
|Power Supply VOLTCRAFT FTPS 5-18W 5 Vdc 3500 mA 17.5 W||Conrad|
This is not the cheapest solution but a stable power supply is crucial for reliable operation of the gateway.
