Arduino MKR GSM 1400 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.

Please note: This board does not ship with a SIM card and Antenna

Arduino MKR GSM 1400 has been designed to offer a practical and cost effective solution for makers seeking to add global GSM connectivity to their 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 external power source from 5V up to 12V. Switching from one source to the other is done automatically. A good 32 bit computational power similar to the Zero board, 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. This is in excess of what can sourced by a standard USB port, so it is MANDATORY to have a 1500 mAh or higher LiPo battery plugged all the time, the current provided by the USB port will be supplemented by the battery.  When powering the board using Vin, a 5V power supply that can supply at least 2A is required.

Warning: Unlike most Arduino & Genuino boards, 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. While output to 5V digital devices is possible, bidirectional communication with 5V devices needs proper level shifting.

Getting Started

You can find in the Getting Started section all the information you need to configure your board, use the Arduino Software (IDE), and start tinker with coding and electronics.

Additional I2C Port

The MKR GSM 1400 has an additional connector meant as an extension of the I2C bus. It’s a small form factor 5-pin connector with 1.0 mm pitch. The mechanical details of the connector can be found in the connector’s datasheet.

The I2C port, also referred to as the Eslov self-identification port within Arduino, comes with: SDA, SCL, GND, +5V, and an extra digital pin meant to send an alarm to the otherwise plain I2C devices connected to it. The pinout is shown in the following image:

If you are interested in designing your own modules for Arduino boards with this expansion port, the connector we suggest using is code: SHR-05V-S-B, also in the picture.
