Overview

The Adafruit Feather nRF52 Pro is another Bluetooth Low Energy board for advanced projects and users who want to use a fully open source Bluetooth Low Energy 5.0 stack. It has a native-Bluetooth chip, the nRF52832, as well as built in USB Serial and battery charging! 

The Adafruit Feather nRF52 Pro ships pre-programmed with the Mynewt serial bootloader that allows you to flash firmware to the device directly from the command-line using the on-board USB Serial converter and the 'newtmgr' tool, so you can get started right away with no additional hardware required. For more advanced debugging, however, you can use a Segger J-Link and the on-board SWD debug connector, which gives you access to a more powerful set of development tools and options.
