KiCAD files for TTN LoRA gateway based on RAK831 and Omega2S
This repository contains the KiCAD CAE files for a RAK831 + Omega2S based TTN LoRa gateway. This PCB can be sandwitched with a RAK831 LoRa concentrator board and fits into a 909060mm IP65 watertight Hammond 1554EGY enclosure.
The firmware for the project (a customized LEDE build) is contained in the plan of the plan44-feed LEDE feed repository in the p44ttngw-config package, see README there about how to build the firmware image from scratch.
