The Arduino MKR GSM 1400 takes advantage of the cellular network as a means to communicate. The GSM / 3G network is the one that covers the highes percentage of the world's surface, making this connectivity option very attractive when no other connectivity options exist. Whether you are looking at building a gateway to your own remote sensor network, or if you need a single device sending a text message when an event happens at the other side of the country, the MKR GSM 1400 will help you to quickly implement a solution to accommodate your needs.

 The board's main processor is a low power Arm® Cortex®-M0 32-bit SAMD21, like in the other boards within the Arduino MKR family. The GSM / 3G connectivity is performed with a module from u-blox, the SARA-U201, a low power chipset operating in the de different bands of the cellular range (GSM 850 MHz, E-GSM 1900 MHz, DCS 1800 MHz, PCS 1900 MHz). On top of those, secure communication is ensured through the Microchip® ECC508 crypto chip. Besides that, you can find a battery charger, and a connector for an external antenna.

The Arduino MKR GSM 1400 is based on the SAMD21 microcontroller.
