obsolete repository - see https://github.com/jeffc/nrf52-watch-firmware
This repo is, at present, a work-in-progress playground for designing and building a smartwatch based on the nrf52840 microcontroller from Nordic.
RayTac MDBT50Q nRF52840 Module Main brains. nRF52840 chipset chosen for BLE capability and low (<1uA) sleep current. This is the module used in the Sparkfun Breakout Sharp LS018B7DH02 1.8" Memory LCD with FLExLight Frontlight Always-on display. Chosen for size and small power consumption. The LS018B7DH02 isn't sold directly by Sharp, and no datasheet is currently available. Unknowns are currently Does the display require 3.3V or 5V power? Does…
