Move-X Cicerone LoRa®/GNSS Board is a high-performance, low-power, Arduino MKR-compatible development board based on the MAMWLE LoRa Module and the u-blox MAX-M10S GNSS Module. The Cicerone Board delivers best-in-class GNSS, long-range wireless connection, and high-performance MCU processing in a low-power solution for optimal battery life.

The Cicerone Board allows users to build tracking applications worldwide with meter-level accuracy and to communicate long-range, low-power data via LoRaWAN®. The integrated Li-Po charging circuit enables the Cicerone Board to manage battery charging through the USB port.

The Move-X Cicerone LoRa/GNSS Board features a compact 63mm x 25mm form factor and is compatible with all Arduino MKR Shield Boards. These boards all share a common pinout to enable developers to easily add expansions with minimal software changes.

“Connector for single-cell 3.7V Li-Po battery (battery shall include protection circuitry against SC, OD, OC)”

What? There’s a battery charge controller on-board yet they cheap-out and do not bother to include a cell protection IC? That’s terrible!

They should have put a nine-cent BRCL3130ME protection chip [1] on the board. Then any cell can be used with it, not just cells with built-in protection. The BRCL3130ME is like the ubiquitous DW01 protection chip [2] but with the two external MOSFETs built-in.
