A plug 'n' play shield for experimenting with monitoring fleets, high-altitude measurements, or any kind of project requiring localization of devices..
Arduino MKR GPS Shield uses the u-blox SAM-M8Q GNSS (Global Navigation Satellite System) module. It is meant to be used on top of boards in the Arduino MKR boards, but thanks to its Eslov connector, it is also possible to hook it up to any board..
It comes with a dedicated library that allows two different interfaces and offers a consistent set of APIs designed for a full usage of the GPS acquired information..
Operating voltage is 3.3V, but this shield comes also with an on-board holder for CR1216 batteries..
The MKR GPS Shield has an additional connector meant as an extension of the I2C bus. The extra I2C port, also referred to as the Eslov self-identification port comes with: SDA, SCL, GND, +5V, and an extra digital pin, meant to send an alarm to the otherwise plain I2C devices connected to it..
