Description :

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. 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! u-blox SARA-U201: Enables GSM / 3G connectivity for the MKR GSM 1400 board. Cortex-M0 32-bit SAMD21: The powerful, low-power processor that is used in all MKR Family boards. ATECC508 crypto chip: The ECC508 crypto chip makes sure your data remains secure and private and can store up to 16 keys in an EEPROM array.
