I chose the parts that I’m going to use, made a schematic, and did most of the CAD. I’m going to use an ESP32 C3 mini, a passive piezo buzzer, a 2.8” ILI9341 LCD, cherry mx style switches with keycaps, and a 100 ohm resistor, along with perfboards. I chose to go with perfboards instead of a PCB because it will be faster, and I think its better because I’m going to be wiring the switches and screen anyway, so there’s no point in paying and waiting for a PCB just to hold the ESP32 and the buzzer. I also did most of the CAD. I might go back and make it look a bit better but I think its fine as is. The only changes I think I may make are closing the sides and giving the screen a bit of an angle.
