Adafruit 2746 Bluefruit LE Shield

Adafruit 2746 Bluefruit LE Shield makes it easy to add BLUETOOTH® Low Energy (BLE) connectivity to any Arduino-based design. The Bluefruit LE Shield connects to the Arduino or a compatible microcontroller board using the hardware SPI-interface (MISO, MOSI, SCK) plus a chip select-line, interrupt-line, and reset. The Bluefruit acts as a data pipe that can transparently transmit back and forth from the iOS or Android device. The Bluefruit LE Shield features Arm® Cortex® M0 core running at 16MHz, with 256KB Flash memory, 32KB SRAM, and an easy AT command set.
