Hacking the Adafruit nRF52840 UF2 Bootloader adding Sugarboat support @NordicTweets @rbaron_

sugarboat is an open source digital hydrometer. The main use case is measuring the amount of sugar in liquids during the process of beer and wine making.

It uses a Nordic nRF52840 microcontroller. Estimated density and sugar content measurements are exposed – along with the temperature, relative humidity, current battery voltage and more – through Bluetooth Low Energy (BLE) services.

To support programming via the built-in USB-C port (via UF2), sugarboat requires a bootloader to be flashed to the chip. This is a one-time operation.

I have forked the Adafruit nRF52 Bootloader and added support to sugarboat.
