1. The Emcraft SOM-NRF9151 Rev 1A module plugged into the SOM-NRF9151-BSB Rev 1A carrier board.

Refer to https://voxelbotics.atlassian.net/wiki/x/BIBHKg for more details.

3. Software Features

This release supports the following key software features:

1. Based on Nordic’s SDK 2.8.0.

2. Adapted Nordic Asset Tracker v2 application.

3. Standard Zephyr Shell.

4. IoT Provisioning, performed on user command from the Zephyr shell.

5. Run-time connection to the Nordic nRF Cloud, with position tracking via GPS.

6. Battery charging when connected to USB Type-C. (Note: only basic battery charging is supported, handling of various error and corner cases remains an open development item).
