IMPORTANT: You must have at least one set of BLE Nano Kit because you will need the companion board, MK20 USB board, which is used to load firmware into BLE Nano from a PC.
Smallest Bluetooth 4.1 Low Energy (BLE) development board in the market
Nordic nRF51822 SoC supports both BLE Central and BLE Peripheral roles
BLE Nano is the smallest Bluetooth 4.1 Low Energy (BLE) development board in the market. The core is Nordic nRF51822 (an ARM Cortex-M0 SoC plus BLE capability) running at 16MHz with ultra low power consumption. Developing a Bluetooth Smart enabled 'appcessory' (accessory device + companion application) is easier than ever. You can quickly produce protypes and demos target for Internet of Things (IoT) and other interesting projects. BLE Nano could operate under 1.8V to 3.3V, therefore it works with a lot of electronic components.
