The Arduino MKR GSM 1400 Microcontroller is a powerful board that combines the functionality of the Zero and global GSM connectivity. It is the ideal solution for makers wanting to design IoT projects with minimal previous experience in networking. It is based on the Atmel SAMD21 and a SARAU201 GSM module. The design includes the ability to power the board using a LiPo battery or an external power source rated 5V. Switching from one source to the other is done automatically.
It is a good 32 bit computational power similar to the Zero board with the usual rich set of I/O interfaces, global GSM communication and the ease of use of the Arduino Software (IDE) for code development and programming. All these features make this board the preferred choice for the emerging IoT battery-powered projects in a compact form factor. 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.
