Red Bear Lab Bluetooth 4.0 Low Energy BLE Shield for Arduino V2.1

This is the Bluetooth 4.0 Low Energy Shield for Arduino Version 2.1 designed by Red Bear Lab.

It is designed to work with Arduino boards, including Arduino Uno, Mega 2560, Leonardo and Due. It allows you to connect your Arduino board with other BLE Central device like a smartphone or tablet.

New Features in BLE Shield Version 2.1

1. Reset button is changed to "side button"

2. nRF8001 SPI pins can be set to either Pins 11-13 on the side or ICSP, this allows other Arduino compatible boards with no ICSP header such as FRDM-KL05 board, RedBoard and so on to interface with the nRF8001 BLE chip

3. Flexible REQN and RDYN pins selectable from pin 2 to 10

4. The board is shorter than before and this allows it to fit on Arduino Yun physically

Requirements:

iOS 6 or 7: iPhone 5 (all models), iPhone 4S, iPad Air, iPad (3rd gen or later), iPad mini (all models) and iPod touch (5th gen or later)

Android 4.3 devices with BLE hardware: Nexus 4, Nexus 7 and Samsung Note 3.
