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.
