The schematic layout started with the ESP-WROOM-32 module at the center. Many of EasyEDA's ESP32 options were for an adapter board, similar to an Arduino, rather than the ESP-WROOM-32, which is still an adapter board of sorts. I added 5V, 3.3V, and ground nets, and then the screen. Displays, like the one I'm using, seem to be cheaper to buy a prefabricated unit with header pin sockets rather than the bare parts, which eliminated some research on my part.

I also added the circuits for a four-way direction pad made of inexpensive 6mm tactile switches and a couple of 12mm for buttons. Each button has a physical pull-up resistor.
