ARDUINO MKR NB 1500

The Arduino MKR NB 1500 is an IoT development board with NB-IoT (Narrowband IoT) cellular connectivity. It uses existing LTE networks to provide low-power wireless communication — faster than LoRa or Sigfox, with quicker wake-up and connection times than traditional GSM/3G, resulting in significant power savings for battery-operated deployments.

Built around the SAMD21 Cortex-M0+ 32-bit MCU with a u-blox SARA-R410M modem and an ECC508 crypto chip for secure communication, the MKR NB 1500 is well suited for remote monitoring and IoT applications where Wi-Fi isn't available.
