Recent source for tags with ST17H66B2 #10

Don't know if this is the right place, but maybe somenone recently got tags with the correct chip.

Beginning of last November I ordered two tags, they use the ST17H66B2 and I was able to run both the uvision built FindMy implementation and the code from this repo built with GCC where I ported the FindMy specific code. Now I recently ordered another 5 tags that looked identical, unfortunately they just arrived with the ST17H66T, which seems to be the OTP ROM variant. Also the bootloader doesn't seem to be present at all, so they are pretty useless.

Before I order another batch with the wrong chip/OTP variant, anyone recently got tags with the correct chip who can share the aliexpress link?

doc.lenze.club seems to have a LeKit 3.0.4.1 for this chip, it's possible that they can be reprogrammed after all. I remember that they are a completely different architecture though, so it is very possible that the flasher in this repo doesn't recognize it at all because it has a different bootloader. Did you try that new LeKit?

I bought two rectangular tags and one circular from Amazon UK (so not AliExpress cheap) this week and both types contained ST17H65's. Which flashed fine and are working with builds of this code and @steve-m's fork.
