What is it?

This module is an autonomous GPS tracker based on an ESP32 processor.

It support regular SIM800 shield to manage 2G GSM communication and it is compatible with most 3.3V based GPS modules. With a dedicated software, the GPS localization of the module can be easily tracked using SMS exchanges or GPS localisation push on a dedicated web server.
