Arduino MKR GSM 1400

Arduino MKR GSM 1400 is ideal for makers wanting to design IoT projects with minimal experience in networking. The board combines functionality of Zero and global GSM connectivity and is based on the Atmel SAMD21 and SARAU201 GSM module. The board features 32-bit computational power, a rich set of I/O interfaces, gobal GSM communication and easy-to-use Arduino Software (IDE) for code development and programming.

The board can be powered by a LiPo battery or 5V external power source. The USB port can be used to supply power (5V) to the board. 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's mandatory to have a 1500mAh or higher LiPo battery plugged all the time. The current provided by the USB port will be supplmented by the battery. When powering the board using Vin, a 5V power supply that can supply atleast 2A is required.
