Cheap Yellow Display (CYD) board

In the past I've used some of the ESP32 boards with a small OLED display on them. It's very handy having the display already there. Recently I saw mention of a "Cheap Yellow Display" (CYD) board with a large colour LCD for AU$20. 

It's a very capable board with extra GPIO available.


My first project was to build an NTP synchronised clock:


It's a resistive touch screen but I'm not sure I'll use that feature.

There's a GitHub repo with helpful software. You do need to grab the User_setup.h file from here and put it in the LCD library directory to get things to work.
