Arduino

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.
