High fidelity images I took of the chip itself for future reference:

Changes from v1:
It was suggested that the (now removed) aliexpress link be run through
archive.org, however aliexpress is incompatible with waybacks scraping tool, and as an alternative I have taken high resolution images of the actual chip I received and put them on archive.org.
The prefix of this patch was changed to Bluetooth: as suggested Maintainers and open lists have been auto CC'd as suggested, via
get_maintainers.pl
Changes from v2:
the commit name has been updated to include the device:vendor id to be clearer
web archive eventually came through so I have readded the link to that aswell
