Arduino Primo Core Wearable Microcontroller

The Primo Core is a low-power coin-sized version of the Primo and is ideal for wearable and compact, in-the-field projects. The Primo Core is a compact Bluetooth device, equipped with a Nordic nRF52832 chip with an integrated motion and environmental sensors. The nRF52832 chip provides Bluetooth Smart (BLE 4.0) and NFC-A tag (Near Field Communication) functions. The low power consumption permits powering the Primo Core with a coin cell battery. The 1.26" diameter Arduino Primo Core can be mounted on a breakout board to extend its functionalities.
