'[EE] 3 or 4 digit Charliplexed 7-segment display'
2017\11\06@203413 by Dwayne Reid

Good day to all.

I've recently purchased some tiny LED digital voltmeters and it looks like the 3-digit and 4-digit LED displays are Charliplexed - the 4 digit display has only 9 connections.

I'd like to find a source for these displays.  I'm okay with driving Charliplexed LEDs and being able to drive a 4-digit display using only 9 port pins is very attractive.

Anyone have any idea where to find these?

Many thanks!
