Implement inexpensive, large-coverage solutions over Narrowband IoT.

Overview

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.

Battery Power

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.

Additional I2C Port

The MKR NB 1500 has an additional connector meant as an extension of the I2C bus. It's a small form factor 5-pin connector with 1.0 mm pitch. The mechanical details of the connector can be found in the connector's datasheet.

The I2C port, also referred to as the Eslov self-identification port within Arduino, comes with: SDA, SCL, GND, +5V, and an extra digital pin meant to send an alarm to the otherwise plain I2C devices connected to it. The pinout is shown in the following image:

If you are interested in designing your own modules for Arduino boards with this expansion port, the connector we suggest using is code: SHR-05V-S-B, also in the picture.

FAQs

Antenna

When purchased at the Arduino Store, the MKR NB 1500 comes bundled with an antenna that can be attached to the board using the existing micro UFL connector. It is possible to use other antennas using the appropriate pigtail.

When purchasing a different antenna than the one provided (or when making your own), please check that it is tuned for the frequency band in use in the LTE range. Also avoid placing your antenna in parallel to a ground plane like a large metallic surface.

Batteries, Pins and board LEDs

  • Battery capacity: Rechargeable Li-Po. Please make sure the battery connector suits your battery. Minimum battery capacity should be 700 mAh, maximum 1500 mAh. The battery-charging chip is programmed with 4 hours of charging time, then it goes into automatic sleep mode. This will limit the amount of charge to max 1400 mAh per charging round. Beware: batteries below 700 mAh should NOT be charged with this board
  • Battery connector: The connector is of type JST S2B-PH-SM4-TB(LF)(SN). Mating connector is JST PHR-2.
  • Vin: This pin can be used to power the board with a regulated 5V source. If the power is fed through this pin, the USB power source is disconnected. This is the only way you can supply 5V (respect this value) to the board not using USB. This pin is an INPUT.
  • 5V: This pin outputs 5V from the board when powered from the USB connector or from the VIN pin of the board. It is unregulated and the voltage is taken directly from the inputs. When powered from battery it supplies around 3.7 V.
  • VCC: This pin outputs 3.3V through the on-board voltage regulator. This voltage is the same regardless the power source used (USB, Vin, and battery).
  • LED ON: This LED is connected to the 5V input from either USB or VIN. It is not connected to the battery power, thus minimizing the impact on battery usage. It is therefore normal to have the board properly running on battery power without the LED ON being lit.
  • Onboard LED: On MKR NB 1500 the onboard LED is connected to D6.
  • Charge LED: This LED is driven by the charger chip that monitors the current drawn by the Li-Po battery while charging. Usually it will lit up when the board gets 5V from VIN or USB and the chip starts charging the Li-Po battery connected to the JST connector. Occassionally, this LED will blink at a frequency of about 2Hz. This is caused by any of the following conditions maintained for a long time (over 20 min):
    • No battery is connected to JST connector.
    • Overdischarged / damaged battery is connected. It can't be recharged.
    • A fully charged battery is put through another unnecessary charging cycle.
