Inspired by, and derived from https://hackaday.io/project/167749-tiny-iv-21-vfd-clock

I copied the HV section from sjm4306's design.


I removed the RTC module as the assumption is that this clock will sync it's time from NTP somewhere.

All of the code and design files are tracked here: https://github.com/cinchcircuits/iv-21-clock-esp32

Please add bugs there.

I decided to load the esp32c3 up with circuit python to make myself learn something about it.

As such, all of the code is in circuitpython.
