Qwiic Alphanumeric Display - missing some specs

These look really good but missing tech info and specs! :roll:

Can you please answer (on the product pages):

-What size is the LED display? i.e. 0.54"

-Do the colons and decimal point work? Some LED displays don’t actually have LEDs there

-Schematic shows 3.3V power but HT16K33 is a 5V IC. I assume it’s a 5V design.
