). I didn't think much of it at the time, but then I heard it referenced again, and again. Then, finally, it was described, and I became interested. 

"Cheap Yellow Display" is the term used for the ESP32-2432S028R. Since this is somewhat challenging to say, and to remember, and since the board is yellow, and it can be obtained for as little as $12 USD, it has been given the nickname "Cheap Yellow Display". I will abbreviate this as CYD for the remainder of this episode. It is an

ESP32 (with built in WiFi & Bluetooth) on a development board with one or more USB connectors, a MicroSD slot, a limited selection of GPIO pins, an RGB LED, a speaker, a light sensor, and best of all, a

2.8-inch (71mm) TFT touchscreen LCD display. 

The CYD runs on 5 volts DC. I am including some photographs of the CYD in the show notes.
