Adafruit Feather nRF52 Pro BLUETOOTH® Low Evergy 5.0 Board

Adafruit Feather nRF52 Pro BLUETOOTH® Low Energy (BLE) 5.0 Board adds wireless connectivity for advanced projects and users who want to use a fully open-source Bluetooth Low Energy 5.0 stack. The Feather nRF52 Pro is based on the  Nordic Semiconductor nRF52 2.4GHz SoC and includes built-in USB Serial and battery charging. The Feather nRF52 Pro is designed to work with the Apache Mynewt operating system, which is released by the Apache Foundation under the permissive and commercial-friendly Apache license. Apache Mynewt includes a number of professionally written networking stacks (BLE 5.0, OIC/OCF, etc.), development tools, and professional project management features like a secure bootloader that allows users to cryptographically sign firmware images and verify them during device updates.  

The Adafruit Feather nRF52 Pro ships pre-programmed with the Mynewt serial bootloader that allows users to flash firmware to the device directly from the command-line using the onboard USB Serial converter and the 'newtmgr' tool. This feature enables the user to start immediately with no additional hardware required. For more advanced debugging, however, a Segger J-Link and the onboard SWD debug connector can be used to access a more robust set of development tools and options.
