Suggestion - Red Led dot matrix display using 5x7 matrixes (5x14, 5x21, 5x28)

Hello,

I have a product suggestion. It’s based on my experience with the “Sparkfun 7-Segment Serial Display - Red”. I’ve used it often when prototyping. I use the ttl interface and it runs at 3.0V, which is the voltage I use for many of my design experiments. So simple, so easy.

My suggestion: A red led matrix display using 5x7 dot modules - but laying them horizontally. eg. making a 5x14, 5x21 or 5x28. A 5x21 display you could still display 5 digits. Such a display could be used to display characters, bar graphs, rolling displays etc. With red leds you could have a display that works at 1.8V, which seems to be needed for a few new designs I’m working on (eg. the excellent I2S microphone TDK T5848 runs at 1.8V).

Thanks for the suggestion! I’ll pass it along to the product team :slight_smile:

Once upon a time, Sparkfun carried these. Not sure why they stopped but it could have been nobody was buying them.

Interesting, thanks, but even if it was available I would still prefer the more compact/efficient 5x14/5x21/5x28 layout. Also, I think it should just require one low voltage micro on the back rather than all those components. If I get more time later on, I will design one, but I thought it was something that others would find useful too - but maybe it is just me …
