The NRF51422-DK is a powerful and capable development solution for wireless application development of the 2.4GHz Bluetooth Low Energy and 2.4GHz proprietary protocols such as Gazell. This DK contains the NRF51422 application processor which acts as the main processor and includes an ARM Cortex-M0 core running at 16MHz. It also contains an on-board radio transceiver and decode/encode logic suitable for Bluetooth Low Energy and proprietary 2.4GHz wireless protocols.

The wireless applications covered by the NRF51422-DK include the basic capability of BLE connectivity and sensor applications such as proximity, sound, motion etc., but also includes many development tools suitable for building custom wireless networks and debugging the applications code.

The main features of the NRF51422-DK are:

• Comprises the NRF51422 SoC, on board transceiver and decode/encode logic
• On-Board Empirical Research Networking (ERNI) protocol & Bluetooth Low Energy Software Stack
• Integrated 2.4GHz RF with integrated BLE stack
• 15 GPIO for direct control of external components and sensors
• Integrated MCU running at 16MHz
• On-board debugger

The NRF51422-DK allows developers to quickly set up wireless application prototypes to draw insights and quickly test out ideas. Mobility, availability of components and integrated wireless network make this kit an ideal tool for developing and prototyping wireless applications for products and system.

The NRF225-DK includes an on-board debugger, which allows the user to debug their application code. This also enables the user to observe the data being transferred across the wireless network in real-time. The integrated debugger also makes it easier to debug many different software layers and protocols used by the NRF51422 SoC. The integrated debugger also facilitates firmware builds, testing and optimization.

The NRF51422-DK also features a range of development tools for building custom wireless networks. For example, the RF ExplorerTM is a tool that allows users to easily diagnose and analyze radio frequencies over a specified area. The RF Explorer also allows users to measure Network Signal Strength (RSSI), signal-to-noise ratio, power levels, RF packet rate, and other factors to determine the performance of wireless networks.

The NRF51422-DK also comes with an integrated BLE stack which allows the user to develop BLE applications. It also includes the proprietary ERNI, which enables users to build and deploy custom wireless networks that support BLE and proprietary 2.4GHz wireless protocols. The integrated ERNI stack gives developers the flexibility to take advantage of existing 2.4GHz wireless technologies and create new applications and solutions at the same time.

In summary, the NRF51422-DK is a powerful and capable evaluation kit and board for developing wireless applications for Bluetooth Low Energy and proprietary 2.4Ghz protocols. It contains a complete set of development tools such as an integrated debugger, RF Explorer, integrated BLE stack, and an ERNI stack to facilitate rapid development, testing and optimization of applications.
