From the project

A0 IoT Gateway

A plug-in expansion module for the A0 base board based on the SIMCom SIM7080G.

The SIM7080G provides NB-IoT / LTE-M (Cat-M) cellular connectivity plus GNSS positioning. Plug it into one of the A0 base board's expansion slots (BUS1 or BUS2) to add a reliable cellular uplink for NB-IoT and LTE-M deployments.

- Cellular: NB-IoT and LTE-M (Cat-M) uplink - GNSS: GPS/GLONASS/BeiDou/Galileo positioning - Interface: connects to the ESP32-C6 over UART via the expansion bus - Power: supplied from the expansion bus
