RP2040 Expansion Card

I’m continuing RP2040 Microcontroller Expansion Card but instead of reviving an old thread, it would make more sense to create a new thread, I’m going to be continuing this idea, but it will not have a customizable cover but instead, a flash chip to store a program. I will post more information and possibly some images.

RP2040s are an amazing platform, but my concern is utility. Are you going to be including any inbuilt interactivity devices like buttons or LEDs?
