Nano ESP32 D0 and D1 pin labelliing

Official Hardware Nano Family Nano ESP32

I was looking at the documentation for the Nano ESP32 and it looks like D0 and D1 are reversed on the pinout document. That is, D1 is on the bottom corner and D0 is above it.

To compare, the Nano RP2040 has these pins labelled as you would normally expect, with D0 in the bottom corner and D1, D2, etc running up from there (forgetting about the RESET and GND pins).

Are D0 and D1 actually reversed on this board, or is this a typo in the pinout diagram? TX and RX labelling is consistent with other boards.

The information I'm looking at is found on the https://store.arduino.cc/products/nano-esp32 page under Documentation, Datasheet in PDF. I did a search for Nano ESP32 D0 D1 Reversed and didn't find anything.

Actually both. Open the first and then click Datasheet. Or just open the second. D1 is in the corner of the board where D0 should be.

That's the way they have always been.
Your expectation for D0 in the corner is one thing, the way they are is another.

all Nano boards have it that way

You're all correct.

I've been going back and forth between the Nano ESP32 and Nano RP2040 and I could swear I saw D0/D1 labelled the opposite way on the RP2040. Must be the pinout copy I saw on the RP2040 was wrong, and that copy must not have come from the Arduino site.

Thanks.
