Kepler Module

The Kepler Module is the heart of the watch. The main board with its CC2640R2F Bluetooth MCU and the OLED display flex; built from the open hardware design and pre-flashed with the latest firmware. Everything the assembled Kepler does, this does: clock, stopwatch, timer, flashlight, on-screen alarm, weather, notifications and the phone features over Bluetooth.

It's for the tinkerer who already has a donor watch and wants to do the swap. You supply the body and a CR2016 cell; the board and display arrive ready to fit and pair.

• Pre-flashed with the current multi-mode firmware
• Phone features via a free, open-source Android app: notifications, music remote, weather, clock sync
  
• The 3D-printable movement holder and assembly notes are part of the package
  

You provide the donor body and coin cell; the case is not included. Android only. No iPhone app yet.
