MKR NB 1500

The Arduino MKR NB 1500 adds Narrowband communication to your projects. It can communicate over NB-IoT and LTE-M networks, and is excellent to use for low-power projects in remote areas. The MKR NB 1500 is also compatible with the Arduino IoT Cloud, making it easy to access wherever you are in the world.

Main Features

The MKR NB 1500 brings NB-IoT / CAT-M1 connectivity to your projects. Using the popular Arm® Cortex®-M0 32-bit SAMD21 processor, it also features the powerful uBlox SARA-R410M-02B 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!

uBlox SARA-R410M-02B

This module can communicate over the LTE-M, NB-IoT and EGPRS networks. It is possible to send and receive SMS, and supports several protocols for sending data over the Internet, including TCP, UDP and HTTPS.

Tech Specs

Here you will find the technical specifications for the Arduino MKR NB 1500.

Please read: operating voltage is 3.3V

The microcontroller on the this board runs at 3.3V, which means that you must never apply more than 3.3V to its Digital and Analog pins. Care must be taken when connecting sensors and actuators to assure that this limit of 3.3V is never exceeded. Connecting higher voltage signals, like the 5V commonly used with the other Arduino boards, will damage the board.

Please read: black conductive foam

You should remove the black conductive foam from the board pins before usage. If you don't remove it, the board may behave erratically.
