Seeedstudio Blend Micro - an Arduino Development Board with BLE

Description:

Blend Micro is our first integrated developement board, we have "blend"ed Arduino with Bluetooth 4.0 Low Energy (aka BLE or Bluetooth Smart) into a single board. It is targeted for makers to develop low power Internet-Of-Things (IoT) projects quickly and easily.
The micro-controller unit (MCU) is Atmel ATmega32u4 and the BLE chip is Nordic nRF8001. Blend Micro runs as BLE peripheral role only, it allows BLE central role devices to establish connection with.
Current supported BLE central devices:
iOS 7
iPhone 4s
iPhone 5 (all models)
iPod touch 5
iPad 3/4/mini/Air
Android 4.3 or above (4.4 recommended for stability) with Bluetooth 4.0 hardware support
Nexus 4
Nexus 7
(please report any other Android devices supported)
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

Feature:

First BLE + Arduino board under Arduino AtHeart program
