This project is a work in progress
LTELink is custom base board design for the Radxa CM3. It main purpose is to connect several IP cameras and other ethernet-connected devices on a drone, and stream their video and telemetry over LTE to a ground station. Additionally, a compatible WiFi adapter could be connected via USB to use WFB-ng for a direct radio link. Video streamed through the LTELink could also be recorded directly to the onboard SD card for a post-flight review.
