Arduino MKR GSM 1400 / ABX00018

TheArduino MKR GSM 1400 is a board based on the Atmel SAMD21 and the GSM module SARAU201. The board was designed specifically to simplify the connection to the global GSM network. It is especially useful for those who have not yet encountered this type of connection. The GSM/3G network covers a large part of the world's surface, which makes this connection option very attractive when no other connection options exist. Whether you are planning to build a gateway to your own network of remote sensors or you need a single device that sends a text message when an event occurs on the other side of the country, the MKR GSM 1400 will help you implement a solution quickly.

This device can charge Li-Po batteries, which means that in addition to charging from an external power source (5V), the board can also operate on battery power. Switching from one source to another is automatic. This model is equipped with good computing power, it also has a rich set of I/O interfaces and a global GSM communication function. In addition, ARDUINO offers its own Arduino Software development environment, which greatly simplifies the entire time-consuming programming process. All of the above makes this platform the best for creating new battery-powered IoT projects.

During cellular data transmission, the current consumption will exceed 500mA. And this is more than a standard USB port can provide, so the main requirement is that a LiPo battery with a capacity of more than 1500mAh is permanently connected to the board. To charge the board using Vin, you need a power supply (5V) that delivers at least 2A.

Note: Unlike most Arduino and Genuino boards, the MKR GSM 1400 operates at 3.3V. The maximum voltage that the I/O pins can withstand is 3.3V. Applying a voltage higher than 3.3V to any I/O pin may damage the board. A standard USB port can be used to supply power (5V) to the board.
