Kepler Module

The Kepler module is the heart of the watch: the main board with the CC2640R2F Bluetooth chip and the OLED display flex, built on the open hardware design and flashed with the current firmware at the factory.

Everything the finished Kepler does, the module does too: clock (settable on the watch), stopwatch, timer, flashlight, on-screen alarm, its own temperature readout, weather, notifications, an image screen, and the phone features over Bluetooth.

Made for tinkerers who already have a donor watch and want to do the conversion themselves. You bring the case and a CR2016 coin cell: the board and display arrive ready to fit and already connected.

• Flashed with the current multi-mode firmware at the factory
• Phone features through a free, open-source Android app: notifications and calls, media control, find phone and find watch, weather, alarm, your own picture, screen order, time sync
• 3D-printable movement holder and assembly guide included

You supply the case and the coin cell; they are not included. Android only; an iPhone app is not available yet.
