Portenta Cat. M1/NB IoT GNSS Shield-board

Portenta Cat. M1/NB IoT GNSS Shield

Unleash global connectivity and localization capabilities of your Portenta or MKR board with the Arduino® Portenta Cat. M1/NB IoT GNSS Shield. This shield enables cellular connectivity to both Cat. M1 and NB-IoT networks with the option to use eSIM technology. Easily track your valuable assets across the city worldwide with your choice of GPS, GLONASS, Galileo or BeiDou.

The Portenta Cat. M1/NB IoT GNSS Shield brings cellular communication and localization on the Portenta H7 boards. The shield leverages a Cinterion TX62 wireless module designed for highly efficient, low-power IoT applications to deliver optimized bandwidth and performance. To use the GNSS functions you will need an antenna like this one.
