ST STEVAL-STRKT01 User manual
Introduction
The STEVAL-STRKT01 LoRa® IoT tracker is designed and optimized to implement the latest technologies in IoT tracker
applications such as asset, people and animal tracking as well as fleet management.
The evaluation board simplifies prototyping, evaluation and development of tracker innovative solutions. It comes with
comprehensive software, firmware libraries, tools, battery, cables and plastic case.
Thanks to the STM32L072CZ embedded in the CMWX1ZZABZ-091 LoRa® module (by Murata), the STEVAL-STRKT01 allows
acquiring position, managing geofence and data logging from Teseo-LIV3F GNSS module and monitoring motion (LIS2DW12)
and environmental (HTS221 and LPS22HB) sensors.
The board also transmits and receives data, configurations and events to and from the cloud over a LoRaWAN™ network, or
stores data locally in the M95M02-DR EEPROM.
The STEVAL-STRKT01 is a LiPo battery operated solution and implements low power strategies thanks to an enhanced power/
battery management design, based on the STBC02 battery charger and the ST1PS01 step-down converter, to ensure long
battery autonomy. The STUSB1600A addresses 5 V USB Type-C port management and offers high voltage protection pins.

2Command list
The STEVAL-STRKT01 supports a set of commands to get information from the system.
Most commands do not need customization, except the ones to set the LoRa device EUI, the LoRa join EUI, the
application key and the network key, the LoRa sending interval and data rate, as well as the RTC date and time.
