SCD41 PIM587 with QR-code?

Does anyone own the breakout-garden SCD41 (SCD41 CO2 Sensor Breakout (Carbon Dioxide / Temperature / Humidity))? If so, can you have a look and check if there is a QR-code on the sensor?

Thanks!

I don’t own one of the Pimoroni boards, but I did buy an SCD41 from Mouser. There’s no QR code. They seem to have stopped doing that at some point.

Thanks. Sensirion should update their datasheet. I was wondering because I did not find any SCD4x with QR-code. Which they claim shows that it is genuine.

Thinking about it, I might have bought mine 18 to 24 months ago, so maybe they’ve only recently started doing the QR codes. At any rate, if bought from a reasonable source it shouldn’t be a problem.

Just for the records: I bought another cheap one from AliExpress, and it does have the QR-code. So this is a hint that your theory about Sensirion starting to add QR codes only recently is correct.

For anyone finding this in the future: according to this PCN, the QR code marking was introduced in 2023.

....
Device marking
A laser marking on the side of the cap will be introduced containing
the product type (e.g. SCD40) and serial number within a QR code.
The laser marking will have no impact on dimensions or function of the cap.
....
Samples of the upgraded SCD41 will be available from February 2023
and shipments from April 2023.
