  • Arg, this is NOT common cathode, it is common anode. As in, I hook up pin 6 (one of the common pins) to +5V VCC and hook up pin 1 to GND via a resistor (one of the segment pins) and the segment lights up. Inverting that wiring and the segment does not light up. When hooking this up to a MAX7219CNG chip, all the segments are lit regardless of display test mode, etc (a common problem when hooking up a MAX7219CNG to a common anode display).

No public wish lists :(
