Bluetooth 4.0 NRF51822 Eval Kit

Product is discontinued.

Product Description

Bluetooth 4.0 is an optimized variant of the proprietary wireless Bluetooth technology standard for data exchange over short distances. Bluetooth 4.0 enhances the Bluetooth technology while sustaining compatibility with classic Bluetooth-capable devices.

Bluetooth 4.0 utilizes low energy technology, enabling manufacturers to incorporate Bluetooth in small battery operated devices. This energy specification is an essential benefit for developers and consumers of handheld and compatible devices.

Bluetooth 4.0 is also known as Bluetooth Smart, Bluetooth Smart Ready and Bluetooth Low Energy (LE).

The NRF51822 Eval Kit is a development and evaluation kit designed for the NRF51822. It consists of the mother board BLE400 and the wireless module Core51822.

BLE400 Features:

  • Onboard battery holder, multi power supplies are available
  • All the IOs are accessible for easy expansion
  • Integrates CP2102 for debugging
  • LEDs and user keys, compatible with other official boards, easy to use
