World's first ARM mbed dev. platform for Bluetooth Smart applications


This product is obsolete. Replaced by nRF51 DK and nRF51 Dongle


The mbed nRF51822-mKIT Evaluation kit is a stand-alone platform for rapid prototyping of Bluetooth® Smart (formerly known as Bluetooth low energy) designs with the nRF51822 SoC. The kit is compatible with the mbed Bluetooth Smart API which simplifies use of the Bluetooth Smart protocol stack.The nRF51822-mKIT gives access to all GPIO pins via pin headers and incorporates a coin-cell battery holder for portability enabling in-situ evaluation and test. Each board has 2 buttons, 2 LEDs, DC/DC converter circuit (optionally enabled in software), power supply and current measurement pins.The nRF51822-mKIT is compatible with a range of mbed software libraries based on the Cortex Microcontroller Software Interface Standard.
