ARDUINO PRIMO

Code A000135

Primo combines the processing power from the Nordic nRF52 processor, an Espressif ESP8266 for WiFi, as well as several board sensors and a battery charger. The nRF52 includes NFC Near Field Communication and Bluetooth Smart. The sensors include an 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 microcontroller architecture, bluetooth low energy BLE , 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 and related internet connectivity functions.

The board has:
• 14 digital input/output pins of which 12 can be used as PWM outputs
• 6 analog inputs
• 64 MHz ceramic resonator
• 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 .

Arduino Primo can be connected to a computer using a cable, or it can be powered using a battery, connected via a connector. Having both Bluetooth and connectivity on board makes it easy to get started in the IoT world
