USB LoRa IoT Interface

2022 - Circuitpython SAMD microcontroller USB dongle for remote sensing

From Sep-2022

The device can be plugged into any USB capable device, which will be mounted as a USB storage device. The storage contains the programming code in Circuitpython, and an index.html, which works as a GUI for controlling the device. The purpose is sending commands via LoRa and receiving measurement results over large distances (km); so basically remote sensing in a tiny pocket format.
