The BLE Nano v2 from RedBearLab is the smallest Bluetooth 4.2/5.0 Low Energy (BLE) development board on the market. With the included DAPLink USB in this kit, you’ll be able to deploy firmware to BLE Nano v2 even easier. At each BLE Nano’s core is a NordicnRF52832, an ARM Cortex-M4F System on Chip (SoC), plus BLE capable of running at 64MHz with ultra low power consumption. The RedBearLab BLE Nano also supports numerous different wireless devices running iOS 7/8, Android 4.3 or higher, and Windows Phone 8.1.
The DAPLink board functions as a USB dongle, accepting 5V from the USB port and regulating it to 3.3V via the onboard LDO, which can be used to power RedBearLab BLE Nano v2. When plugged into your computer, the USB board will appear as both a serial port and a removable mass storage disk.
Developing a Bluetooth Smart-enabled ‘appcessory’ (accessory device + companion application) is easier than ever. You can quickly produce prototypes and demos targeted for Internet of Things (IoT) and other interesting projects. The RedBearLab BLE Nano v2 can operate under 1.8V to 3.6V, making it able to work in conjunction with a wide variety of electronic components. Since the RedBearLab BLE Nano v2 can work as low as 1.8V, the DAPLink USB board has been designed to run at 1.8V as well. All you need to do to get the USB board to run at 1.8V is short the switch S. Then the regulator will output 1.8V instead, allowing your Nano to work with applicable components.
If a board needs code or communicates somehow, you're going to need to know how to program or interface with it. The programming skill is all about communication and code.
Skill Level: Competent - The toolchain for programming is a bit more complex and will examples may not be explicitly provided for you. You will be required to have a fundamental knowledge of programming and be required to provide your own code. You may need to modify existing libraries or code to work with your specific hardware. Sensor and hardware interfaces will be SPI or I2C.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Rookie - You may be required to know a bit more about the component, such as orientation, or how to hook it up, in addition to power requirements. You will need to understand polarized components.

I got the great bear lab nano because of the ultra small BLE form factor. I followed instructions to download preferences libraries etc. After a few steps I realized I have lost my adafruit libraries and example sketches. I am using Arduino IDE v1.7 on the Mac Yosemite OS. I will now have to reconstruct all these sketches and libraries. Oh, well.
A great way to prototype BLE apps. Works with Nordic SDK and Arduino. Lot easier to use than other NRF eval boards.
