Arduino® PRIMO Core
The Primo Core is the little brother of the Primo with a Nordic nRF52 processor.
The Primo Core is a low-power, coin-sized version of the Primo, ideal for wearables.
The Primo Core is a compact Bluetooth device with a Nordic nrf52832 chip and motion and environmental sensors. The low power consumption allows the Primo core to be powered by a coin cell battery. The Arduino Primo core can be mounted on a breakout board to expand its functionality, the so-called Alice Pad.
