Arduino® PRIMO
The Primo is the first Arduino board with a Nordic nRF52 processor featuring WiFi.
The Arduino Primo combines the computing power of the Nordic nRF52 processor, 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 Core was developed in collaboration with Nordic Semiconductor for the IoT sector and is ideal for wearables projects thanks to its low power consumption and Bluetooth capability. The microcontroller used is an nRF52832. This is also used on the Arduino Primo.
