The Arduino MKR NB 1500 development board is a MKR board that takes advantage of the NB-IOT (Narrow-Band Internet of Things) and LTE CAT M1 cellular bands. These specific bands have been allocated for connected devices. The board uses U-Blox's SARA modules and is fit for global use on Vodafone, AT&T, T-Mobile USA, Telstra, and Verizon (Bands 2, 3, 4, 5, 8, 12, 13, 20, 28).
The board is perfect for field-type applications or long range wireless communication. The board also features an on board crypto-security chip.
