The Arduino MKR GSM 1400 is a development board based on the Atmel SAMD21 and a SARAU201 GSM module. It combines the functionality of the Arduino Zero board with global GSM connectivity. This Arduino MKR GSM 1400 comes with headers on board.

The Arduino MKR GSM 1400 is perfect for those who are newer to networking. Use the MKR GSM 1400 to set up you IoT projects with global GSM connectivity with ease. The Arduino website has tonnes of resources on “Getting Started” with your board. If you are ever stuck, or have a question, the Arduino community is there for support.
