Hi Guys! Hope you’re well today. Happy to see you around. In this post today, I’ll walk you through the Introduction to Arduino MKR NB 1500. The Arduino MKR NB 1500 is mainly developed for working in remote areas where no power or internet connection is available. This board is based on a SAMD21 Cortex-M0+ 32bit low power microcontroller and comes with an operating voltage of 3.3V. Admit it. The Arduino board is a remarkable addition to the development of many automation and embedded projects. These boards are incorporated with a series of digital and analog pins that can be connected with the expansion boards or other breadboards. Most of the Arduino boards are integrated with 8-bit Atmel AVR microcontrollers. And all these boards incorporate different flash memory size to store the code. The two-way serial communication is added in the boards and some boards are given with the facility of the USB port that is used for the direct connection with the computer systems and to program and test the boards on the go. Arduino is an open-source platform that means you can edit and modify the hardware and software based on your requirements. The Arduino IDE software is used to program all kinds of Arduino boards. These boards are programmed using C and C++ language. I suggest you read this post all the way through, as I’ll walk you through the Introduction to Arduino MKR NB1500 covering datasheet, pinout, features, programming, pin description, and applications. Let’s jump right in.

Introduction to Arduino MKR NB 1500

  • The Arduino MKR NB 1500 is an Arduino board based on the SAMD21 Cortex-M0+ 32bit microcontroller that is mainly developed for applications in remote areas with no power or internet connection. On-field monitoring systems use these Arduino boards.
  • These are 22 digital I/O pins incorporated on the board. 7 analog and 12 PWM pins are also included in the chip.
  • The Rx and Tx pins are added to the board for the UART serial communication where Rx is used to receive the serial data and Tx is used to transmit the serial data.
  • Moreover, I2C and SPI communication protocols are also included in the device.
  • The power delivered to the board by USB is 5V. Plus, the board also incorporates a Li-Po charging circuit that makes the board run in two ways: either from the external 5V source or from battery power.
  • The clock speed of the oscillator is 32.768 kHz (RTC), 48 MHz which is required for the synchronization of the internal functions.

  • You can also interface the micro-sim with the board, however, micro-sim is not provided with the board. You need to purchase it separately.
  • You can interface breadboard with this board, giving you the ability to actually test and run your project on a breadboard before switching to the PCB design of the electrical circuit.
  • The board’s flash memory is 256KB. And it doesn’t incorporate EEPROM memory while the SRAM memory is 32KB.
  • The Arduino Program (sketch) is stored in the flash memory and SRAM memory is used to generate and manipulate variables when it runs.

Arduino MKR NB 1500 Datasheet

Before you apply this device to your electrical project it’s better to scan through the datasheet of the device that features the main characteristics of the board. You can download the datasheet of Arduino MKR NB 1500 by clicking the link below.

Arduino MKR NB 1500 Pinout

The following figure shows the pinout diagram of Arduino MKR NB 1500.

There are three LEDs on the board. One is a built-in LED, and the other power LED and battery charger LED.

Arduino MKR NB 1500 Pin Configuration

Hope you’ve got a brief idea about this board. In this section, we’ll discuss the pin description of the pins incorporated on the board.

Digital I/O Pins

There are total 8 digital I/O pins integrated on the board which you can use as an input or output according to the requirements. They remain either HIGH or LOW. When they are HIGH they receive 5V and when they are LOW they receive 0V.

Analog Pins

There are total 7 analog pins incorporated on the board. As they are analog pins, they can get any number of values in opposed to Digital pins that only get two values i.e. HIGH or LOW

PWM Pins

The board comes with 12 PWM pins on board. When these pins are activated, the board generates analog result with digital means.

SPI Pins

This board incorporates SPI (serial peripheral interface) pins that are mainly employed to develop the communication between the controller and other peripheral devices such as sensors or shift registers.

Two pins… MISO (Master Input Slave Output) and MOSI (Master Output Slave Input) are used for SPI communication. These pins are used to receive or send data by the controller.

I2C Pins

I2C is a two-wire communication protocol. That uses two lines i.e. SDA and SCL. The SDA is a serial data line mainly used to carry the data while SCL is a serial clock line mainly used for the synchronization of all data transfer through the I2C bus.

UART Pins

This device supports UART serial communication. Two pins Rx and Tx are used for the transmission and receiving of serial data.

Battery Connector

If you want to power up the board with the battery be sure to find the female 2 pin JST PHR2 Type connector. Polarity:  while you look at the board connector pins… Polarity is Left = Positive and Right = GND Vcc – This pin generates 3.3V using the on-board voltage regulator. 5V – This pin generates 5V when powered from the Vin pin of the board or from the USB connector. Vin – This pin provides power to the board using a regulated 5V source. If you supply power using this pin, the power through the USB port will be disconnected. This way you can power the board not using USB.
