ESP32 pinout uses RX2/TX2 pins

I’m making a PCB and I’m wondering is it ok to change Red and Blue data pins from 16/17 (which are also RX2/TX2 that can be used with hardware serial) to some other IO pins? Are there any requirements for those pins?

Any GPIO that doesn’t have a conflict should be fine

I’ll submit another wiring option as pins 16/17 are also used for PSRAM and I also have a wiring I can share and submit as a patch

@jaroslav try my new wiring submitted for inclusion in

@Louis this should be a no-op for existing users.
