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.
Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
