Description of product
Add Narrowband 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 like on-field deployments, remote metering systems, solar-powered devices, or other extreme scenarios.
The board's main processor is a low power Arm® Cortex®-M0 32-bit SAMD21, like in the other boards within the Arduino MKR family. The Narrowband connectivity is performed with a module from u-blox, the SARA-R410M-02B, a low power chipset operating in the de different bands of the IoT LTE cellular range. On top of those, secure communication is ensured through the Microchip® ECC508 crypto chip. Besides that, the pcb includes a battery charger, and a connector for an external antenna.
This board is designed for global use, providing connectivity on LTE's Cat M1/NB1 bands 1, 2, 3, 4, 5, 8, 12, 13, 18, 19, 20, 25, 26, 28. Operators offering service in that part of the spectrum include: Vodafone, AT&T, T-Mobile USA, Telstra, and Verizon, among others.Its USB port can be used to supply power (5V) to the board. It has a Li-Po charging circuit that allows the board to run on battery power or an external 5 volt source, charging the Li-Po battery while running on external power. Switching from one source to the other is done automatically.
The Arduino MKR NB 1500 is based on the SAMD21 microcontroller.
