RedBear Lab BLE Nano with MK20 USB board is the new application+accessory in one unit.
Bluetooth Low Energy is said to be an effective device for all IoT applications.
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.
Current supported BLE central devices:
Android 4.3 or above (4.4 recommended for stability) with Bluetooth 4.0 hardware support
Windows Phone 8.1
Windows 8.1 with built-in Bluetooth 4.0 or USB dongle
Mac OSX 10.9.2 with built-in Bluetooth 4.0 or USB dongle
Linux with BlueZ 5.1 with built-in Bluetooth 4.0 or USB dongle
There are three options to program your BLE Nano with MK20 USB Board.
Nordic nRF51822 BLE SDK
If you want the full power of nRF51822, you should use Nordic nRF51822 BLE SDK, we provide a product key for all registered users* of our BLE Nano to download the SDK.
We have prepared a guide "Firmware Development with nRF51822 SDK" to show you how to use the SDK with ARM GCC.
mbed's Bluetooth Low Energy API
The mbed platform, developed by ARM, provides free software libraries and online tools for professional rapid prototyping of products based on ARM microcontrollers. Their Bluetooth Low Energy Development Team has released the mbed BLE API together with some samples. Our "Getting Started with nRF51822" guide shows you how to start programming with mbed.
Arduino Library for nRF51822
We have developed an Arduino library for nRF51822 which will be open-sourced and publicly available in the future; it is still at pre-release stage but we invite all interested registered users* of our BLE Nano to access the pre-release library. Please refer to our "Getting Started with nRF51822" guide for more details.
* You will find a product registration card inside the BLE Nano box with the instruction on how to register.
1.8V to 3.3V
Cause: Use either one power source ata atime, otherwise you will damage the board.

MK20 USB Board
The MK20 (Freescale MK20DX128VFM5) USB board acts as a dongle, it accepts 5V from USB port and regulates to 3.3V via the onboard LDO which can be used to power BLE Nano. It appears on your computer as both a serial port and a removable mass storage disk. Please refer to the guide Getting Started with BLE Nano to learn how to deploy firmware using MK20 USB board.
Since the BLE Nano can work as low as 1.8V, we have designed the MK20 USB board to run at 1.8V as well, simple short the switch S, then the regulator will outputs 1.8V instead. This would allow your BLE Nano to work with 1.8V components.
