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 NFCSTM32f103, a service microcontroller used for advanced debugging and programming of the other microcontrollersESP8266, 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.
