Original GitHub issue: https://github.com/OpenEPaperLink/OpenEPaperLink/issues/484

Can you use an esp32-s3 with no display and a esp32-c6 to make an Spaghetti AP?, don't need a display, but the pinout on the non display version doesn't have pin 19 or 47, there is a RST, can this be done?

Thanks

According to this page Pin 19 is debug-txd which isn't critical but is VERY handy when things don't work. Like when your building AP from scratch.

Pin 47 is RST so you're good there.

If I were you I'd order the correct board they are cheap and might save you some grief.

The display isn't essential, but like the debug port it can be very handy.
