Sparkfun SparkFun MicroMod Asset Tracker Shield
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 Shields for more details).
Programming
Set --shield sparkfun_carrier_asset_tracker when you invoke west build. For
example:
# From the root of the zephyr repository
west build -b micromod/nrf52840 --shield sparkfun_carrier_asset_tracker samples/net/cellular_modem/
