Any information about the QR code on WROVER-B?

Postby vonnieda » Thu Jun 27, 2019 4:48 pm

Hi all,

Can anyone tell me what information is encoded in the QR code visible on the WROVER-B modules?

I scanned some, and here's an example of what I got: 053210201810001201842000586EESP0XXXX

The part looks like a date code, and the last part obviously says ESP, and I see another 2018 in there that might be part of a date.

The reason that I ask, is that I'm trying to find a good way to read the EFUSE MAC address during PCBA and I was hoping I could just get it out of that QR code. It looks like the answer is probably "no", but I'm still interested to know what's in the code.

Thanks,
Jason

Hi Jason,
we recently issued a PCN about the QR code of the ESP32-WROVER-B
After 19 June the QR code will be as follows: Fab code(2-digit)+YYWW(4-digit)+MAC(12-digit), 18 digits in total
It seems Factory read your mind :lol:
I can send you the PCN in PM if you need it, but there's not much more than what I wrote above.
Thank you for selecting the ESP32.
Ciao! Franco
