Arduino MKR NB 1500 / ABX00019

TheArduino MKR NB 1500 is a board based on the SAMD21 microcontroller with a low-power Cortex-M0 32-bit processor. This controller provides a wide range of available interfaces such as I2S, I2C, UART and SPI.

The board operates at 3.3V and offers 22 digital I/O, 12 PWM outputs, and seven analog inputs. However, the most important feature of this device is that the board is equipped with NB-IoT technology, which provides fast communication using the LTE cellular network. The narrowband connection is made using a module from u-blox - the low-power SARA-R410M-02B chipset, which operates in different bands of the IoT LTE cellular range. In addition, secure communication is ensured by the Microchip® ECC508 cryptographic chip. In addition, the board has a charger and a connector for connecting an external antenna. This board is designed for global use, providing connectivity in the LTE Cat M1/NB1 bands 1, 2, 3, 4, 5, 8, 12, 13, 18, 19, 20, 25, 26, 28.

It also stands out because it has a lower impact on energy consumption compared to GSM or 3G. Based on all of the above, we can conclude that this device is ideal for use in places where there is no stable Internet connection or power supply, such as in remote measurement systems, as well as in those that provide power from solar panels.

Purpose of the board connectors:

The MKR NB 1500 has an additional I2C port designed to expand the I2C bus. This is a 5-pin small form factor connector with a 1.0 mm pitch. Mechanical details of the connector can be found in its technical description. The I2C port, also called the Eslov self-identification port in Arduino, comes with: SDA, SCL, GND, +5V and an additional digital pin designed to send an alarm signal to simple I2C devices connected to it. The pin assignments are shown in the image:
