A 3D printed clock driven by a single stepper motor using gears to separate hours, minutes and seconds.

This build replaces the electronics used in the Simple Super Gear Clock by Tokyo_Bird. The Arduino Nano module and ULN2003A stepper motor driver module has been replaced with a ATtiny1614 microprocessor and 4 MOSFETs. All components are surface mount and fit on a board with the same form factor as the Arduino Nano module.”
