some things I'm seeing online say that additional components are needed? Is the circuitry still the same if I don't have the speaker wired in?
this is weird , can you send me a picture of your setup, please?

I have a nodemcu esp-32s and a devkit esp32 and both don't work.
The thing is, I used to have a esp32 that did work with the pn532 and I think it was one of these devices. I'm not sure if I upgraded esphome and it broke, or if something bad happened to this board?
sometimes the version IS able to be retrieved, but often not.
