I would suggest getting the exact version of the ESP32 Dick is talking about as there are some differences between boards in the ESP32 family so pin-outs are not identical. Indeed, some pins do strange things on boot before they revert to a normal I/O pin.

There is a nice breadboard similar to a UNO style for Arduino.? I have attached a pix of the 30 pin version which is the most popular.? There also is one for the 38 pin.? Amazon has some but Ali Express has a better selection of suppliers, some as low as $2 or kits with a ESP32 30p / 38p Expansion Board and an ESP32 development board.
