Nordic nRF52840-DK

The nRF52840 Development Kit is a single-board development kit for Bluetooth low energy, ANT, 802.15.4, and 2.4 GHz proprietary applications using the nRF52840 SoC.

The kit is compatible with the Arduino Uno Revision 3 standard, making it possible to use third-party shields that are compatible with this standard together with the kit.

BLE stack

Nordic Semiconductor provides a wireless protocol stack called the SoftDevice. The SoftDevice is precompiled into a binary image and functionally verified according to the wireless protocol specification, so that all you have to think about is creating the application.

compiled binary size

For the default DK mbed target, any mbed build tools (online IDE, mbed CLI) will put the SoftDevice and the user application together into a binary file intended to program your development kit. Be aware of the SoftDevice size – it adds more than a hundred KB to any compiled binaries.

Further information about the type of Nordic’s target is available in nRF5 ReadMe.
