Arduino Primo nRF52 ESP8266 WiFi Bluetooth Microcontroller

The Primo is the first Arduino board designed with a Nordic nRF52832 32-bit ARM processor with integrated Bluetooth Smart Low Energy (BLE) and NFC-A tag Near Field Communication (NFC), an Espressif ESP8266 for WiFi and several on board sensors and a built-in battery charger. The 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 start experimenting with IoT projects.
