###############################################

Overview
********

The SparkFun MicroMod Asset Tracker Carrier Shield is part of the Sparkfun
Micromod standard, a modular interface ecosystem that uses the M.2 standard
to mix and match your choice of processor with specific Functions Boards.

The Asset Tracker Carrier Shield is built around the u-blox SARA-R510M8S
module, which offers Secure Cloud LTE-M and NB-IoT data communication for
multi-regional use and GNSS capabilities via an integrated u-blox M8 GNSS
receiver for accurate positioning information.

Besides, this shield has an integrated ICM-20948 Inertial Measurement Unit
(IMU) for Nine Degree-Of-Freedom, a built-in micro-SD card socket for data
logging as well as a nano SIM card port.

Requirements
************

This shield can only be used with a board which provides a configuration for
Micromod connectors and defines node aliases for UART, I2C and SPI interfaces (see
:ref:`shields` for more details).

Programming
***********

Set ``--shield sparkfun_carrier_asset_tracker`` when you invoke ``west build``. For
example:

.. zephyr-app-commands::
   :zephyr-app: samples/net/cellular_modem/
   :board: micromod/nrf52840
   :shield: sparkfun_carrier_asset_tracker
   :goals: build
