MKR GSM 1400

End of Life

The Arduino MKR GSM 1400 is a great starting point for building IoT projects connected to GSM / 3G network. Whether you are looking at building a sensor network for agricultural projects, or for urban data collection, the MKR GSM 1400 is your go-to board for IoT projects when Wi-Fi is not available.

GET STARTED

Main Features

The MKR GSM 1400 is a great option for GSM / 3G connectivity projects. Using the popular Arm® Cortex®-M0 32-bit SAMD21 processor, it also features the powerful u-blox SARA-U201 module and the ECC508 crypto-chip for security. The board is part of the MKR family, where you can choose from a large variety of shields to build projects out of the box with minimal effort!

Tech Specs

Here you will find the technical specifications for the Arduino MKR GSM 1400.

Please read: operating voltage is 3.3V

The microcontroller on the this board runs at 3.3V, which means that you must never apply more than 3.3V to its Digital and Analog pins. Care must be taken when connecting sensors and actuators to assure that this limit of 3.3V is never exceeded. Connecting higher voltage signals, like the 5V commonly used with the other Arduino boards, will damage the board.

Please read: black conductive foam

You should remove the black conductive foam from the board pins before usage. If you don't remove it, the board may behave erratically.
