The new standard Narrow Band IoT, with the easy to use Arduino ecosystem. Fully compatible with Narrow Band IoT NB classes and LTE CAT M1 networks.
Add Narrow Band communication to your project with the MKR NB 1500. It's the perfect choice for devices in remote locations without an Internet connection, or in situations in which power isn't available (e.g., field monitoring systems).
This board is designed for global use, providing Cat M1/NB1 deployed bands 2, 3, 4, 5, 8, 12, 13, 20, 28 (Vodafone, AT&T, T-Mobile USA, Telstra, Verizon).
