The MKR GPS Shield is based on the u-blox SAM-M8Q GNSS (Global Navigation Satellite System) module.

This module is designed to operate with different positioning services concurrently. It receives and processes the signals from GPS, GLONASS and Galileo. It interfaces with Arduino boards either through a serial interface, when used with headers and put on top of a MKR board, or through an I2C interface and a dedicated ESLOV cable supplied as bundle.

Our Arduino_MKRGPS library handles the two different interfaces and offer a consistent set of APIs designed for a full usage of the GPS acquired information

The Arduino MKR GPS Sheld is open-source hardware! You can build your own board using the following files:

Please note: Galileo reception is disabled by default, but can be enabled by sending a configuration message (UBXCFG-GNSS) to the receiver. You can find a detailed description of the protocol here.
