The Arduino MKR GSM 1400 is a powerful and feature-packed board that combines the functionality of the Arduino Zero with global GSM connectivity. For those wanting to design IoT projects that have GSM connectivity, and have little or no experience in networking, it is a practical and cost effective solution.
The board is based around the Atmel SAMD21 MCU with a SARAU201 GSM module, all in the compact MKR form factor. The board is powered from a LiPo battery (not supplied) or via external 5V power source, with automatic switching from one source to the other.
The MKR GSM 1400 features 32 bit computational power, along with a rich set of I/O interfaces, global GSM communications, and the ease of use of the Arduino IDE for code development and programming. Combining the compact form factor, the excellent Arduino functionality and the global GSM connectivity, you get a board that is the preferred choice for IoT battery-powered projects in a portable form factor.

Caution: The MKR GSM 1400 runs at 3.3V. The maximum voltage that the I/O pins can tolerate is 3.3V. Applying voltages higher than 3.3V to any I/O pin could damage the board.
Caution: During cellular transmissions the peak current required by the board will exceed 500mA. This is in excess of what can sourced by a standard USB port, so it is MANDATORY to have a 1500mAh or higher LiPo battery plugged all the time. When powering the board using Vin, a 5V power supply that can supply at least 2A is required.
