Hi,
I purchased 3 HT16K33 14-Seg QT boards. Order ID: 2920013-9204963355
I'm receiving 'RuntimeError: No pull up found on SDA or SCL; check your wiring'
As was suggested to a poster on Sept. 18th, I may have the rev B of these boards [see attached pic].
I'm willing to try the suggested remedy of jumping Vio and VHi on the pin headers before asking for a replacement, if it doesn't interfere with chaining them w/stemmaQT.
If you could please draw on my pic what I should jump, I'll give it a go.
Thanks!

We can just replace these. Just to check - were all 3 ordered the rev B variant?

Yes, all 3 were the same. One not shown soldered up to segments :^)

Send an email to [email protected] with a link to this thread and your order number and they can send you 3 new LED Backpacks (PID 1910). Also mention the LED that's already soldered and they can replace that too.
