Show HN: F32 – An Extremely Small ESP32 Board

As part of a little research and also some fun I decided to try my hand at seeing how small of an ESP32 board I can make with functioning WiFi.

This is a very cool experiment, even if the board doesn't end up being that practical (the antenna hack is going to be an ongoing issue I think) your documentation looks great at a glance!

Thank you! I agree, antenna definitely needs some improvement.
