The Arduino Primo is the first Arduino board featuring a Nordic nRF52 processor with WiFi. It combines the processing power from the Nordic, an Espressif ESP8266 for WiFi, as well as several on-board sensors and a battery charger. The nRF52 includes NFC (Near Field Communication) and Bluetooth Smart. The sensors include an on-board button, LED and infrared receiver and transmitter.

The Arduino Primo is the first board developed in cooperation with Nordic Semiconductor. It brings new benefits for the IoT world all on one platform; Advanced 32-bit microcontroller architecture, bluetooth low energy (BLE), Wi-Fi, near-field communications (NFC), and infrared (IR) transmit and receive capability.

There are three onboard microcontrollers:

  • nRF52832, the main Arduino microcontroller with integrated BLE and NFC
  • STM32f103, a service microcontroller used for advanced debugging and programming of the other microcontrollers
  • ESP8266, for Wi-Fi and related internet connectivity functions.

Arduino Primo can be connected to a computer using a micro-USB cable, or it can be powered using a battery, connected via a 2-pin JST-PH connector. Having both Bluetooth and Wi-Fi connectivity on board makes it easy to get started in the IoT world.

Features:

  • 14 digital input/output pins (of which 12 can be used as PWM outputs)
  • 6 analog inputs
  • 64 MHz ceramic resonator
  • Micro-USB connector
  • ICSP header
  • Battery charger
  • Infrared receiver and transmitter
  • NFC antenna
  • BLE interface
  • Buzzer
  • Two service buttons
  • LEDs
  • Reset buttons (to reset the various microcontrollers)

    • Power

      The Arduino Primo can be powered three different ways:

      • using a micro-USB connector
      • connecting a power supply to the Vin pin
      • using an external battery connected via the 2-pin JST-PH connector.

      Memory

      The nRF52832 has 512 KB of Flash memory and 64 KB of SRAM. There is no onboard EEPROM memory.

      Communication

      The Arduino Primo has a number of facilities available for communicating with a computer, tablet, or smartphone; another Arduino; or other microcontrollers and devices.

      Programming

      The Arduino Primo can be programmed with the Arduino IDE software, as well as 3rd party software. The Arduino is available from Arduino IDE 1.8.x version, downloading the corresponding platform (Arduino NRF52) from the Board Manager.
