I’ve just designed a RPI hat using SX1301/8: https://github.com/will127534/LoRa-concentrator
I guess it is the first OpenSource Real LoRa Gateway
If anyone is interested, here is the link to Tindle store : https://www.tindie.com/products/will123321/sx1308-raspberry-pi-lora-gateway-board/
Also note that I’ve also designed a version for RPI Zero, which I think the smallest Gateway using SX1301?
Using it as my Portable Gateway mainly for debug though. Love the USB Ethernet Gadget device.
