Assembly

Solder socket headers to the EYESPI BFF. Solder plug headers to the QT Py.

Plug in the RTC breakout to the QT Py using a STEMMA QT cable.

Insert an EYESPI cable into the eInk display.

Attach the eInk display to the mounting holes on the 3D printed stand using M2.5 stand-offs and screws. Make sure to run the EYESPI cable through the display cutout.

Plug the EYESPI cable into the EYESPI BFF.

Plug the QT Py into the EYESPI BFF so that the 3D printed hook is sandwiched between them. Make sure that the QT Py USB port is above the BFF EYESPI connector.

Use an M2.5 screw and stand-off to attach the RTC breakout to the top right eInk display stand-off.

That completes the assembly! Power up the QT Py with a USB cable and never be wrong about the date or day of the week again.
