Nordic Semiconductor recently announced that Arduino’s new Arduino Primo features its nRF52832 Bluetooth low energy SoC. The IoT-targeted Arduino Primo PCB features native Bluetooth low energy wireless connectivity and includes Near Field Communication (NFC), Wi-Fi, and infrared (IR) technologies. In addition to being able to wirelessly connect to a wide array of Bluetooth low energy sensors, the Arduino Primo uses the nRF52832 SoC’s integrated NFC for secure authentication and Touch-to-Pair (a simple BLE pairing function requiring no user interaction), and has embedded IR for traditional remote control.
The Nordic nRF52832 SoC’s ARM processor has ample computational overhead to manage the Arduino Primo’s on-board accelerometer, temperature, humidity, and pressure sensors. The Nordic Semiconductor nRF52832’s features and specs include:
- 64-MHz, 32-bit ARM Cortex-M4F processor
- 2.4-GHz multiprotocol radio that’s fully compatible with the Bluetooth 4.2 specification and features –96-dB RX sensitivity and 5.5-mA peak RX/TX currents
- 512-KB flash memory and 64-KB RAM, and a fully-automatic power management system to optimize power consumption.
You can program via the Arduino Integrated Development Environment (IDE) programming interface. If you want to access the Arduino Prio’s most advanced features and functionality, you can use any Nordic nRF52 Series-compatible Software Development Kit (SDK) or programming tools. For example, the nRF5 SDK for IoT enables you to develop IPv6 over Bluetooth low energy applications on the nRF52832 SoC.
