I'm confused. Why have two separate places to suggest modules? In my opinion, using the forum to suggest them makes the most sense so people can debate specs/implementation details and the best (compromised) solution can come out of it and hopefully be useful for more people. Did I miss something?
Having said that, it seems a few people would want a screen module of some sort. If you Google
arduino lcd, there are all types of screens - just numbers, alphanumeric multi-line ones, and full RGB ones. Personally, I could see integrating any of those in my keyboard project -- they'd all be useful to different degrees.
I saw someone else suggested basically a DisplayPort/HDMI/VGA Out module. I have no use for it but can see the utility.
