nRF51 DK for IoT development with Bluetooth low power

I had a change to get the NRF51 DK board and test it. I think it's GREAT. The board size is similar with Raspberry Pi B+ but the computing power is less than Raspberry Pi.
The nRF51 is designed for IoT controller with Bluetooth low power (BLE). It has nRF51422 chip which has ARM Cortex-M0 32bit, 256k flash memory, 32k  sram and 2.4GHz transceiver which support BLE, ANT+ and other 2.4GHz RF.

BLE is most popular connectivity interface for IoT platform. So nRF51 DK board is best for IoT device. It has many document and examples on the web-site and the community is very popular.

The BLE and 2.4GHz RF is controlled by SoftDevice library. and the application can use it through API. So anyone who is not familiar with BLE can easily handle it.

It has J-Link debugging interface so you can use J-Link debugging tools without any other J-Link HW and It is mbed enabled device. That means you can control nRF51 device using ARM mbed platform.
