The pin 1 dot wouldn't line up with pin 1 if it was on the 14 pin side...
Cheers
hi hans
you have the ESP32-D2WD Q5 too ?
i know, the skizze in the docu point with pin1 to the 14 side
but then one of the diagram is wrong cause like you see
Q6

Q5
- q5.png (80.91 KiB) Viewed 14007 times
in the Q5 must then a mistake in the datasheet, or not?
..

Exactly, it seems the QFN 5x5 has a mistake in the datasheet. The mechanical drawing matches the physical part, so that would mean pin 1-10 are where the current pinout drawing has pins 11-20. Can someone from Espressif confirm?

So either pin 1 is on the 10-pin side and numbering is clockwise or pin 1 is on the 14-pin side and numbering is anticlockwise? Numbering shown from (rotated) bottom view by mistake?

Numbering is always counter-clockwise, so I think we have to assume the pinout diagram is off by 90 degrees...

Seems like a mistake, will get this fixed, sorry about that.

Thanks. Can you confirm my interpretation is correct, ie. pins are counter-clockwise and start on the long side?

Yes, pin 1 is on a 14 pin side, numbering is counter clockwise (if looking from the top).

How long of a wait ? Need this info to finalize PCB design

I would appreciate an answer within a short timeframe, too. Our finished design is now waiting for more than a month when I opened this topic on March 04. In addition I would be happy when I could get some information concerning the availability or planned availabilty of the QFN48 5x5 parts. I contacted sales and was transferred to the distributor which is responsible for my region. However I can not get an answer concerning this topic from this company. It seems that they just want to sell our company the QFN48 6x6 parts of the old silicon revision. Even if they know that we have started the project with two different parts in parallel and the PCB with the other chip is already in our software department.
