The Project: A tiny, 2.5" OLED screen attached to a jacket that displays an album of images and videos

I have a Cyberpunk style jacket that I want to accessorize by adding a small OLED display. I want the display to show a slideshow of images and videos stored in a memory card.

I want to add two buttons to work as go to next and go to previous buttons.

The questions:

• What board would work best? Will a Raspberry Pico be enough for this? It doesn't look like the Pico has a memory card slot.
• My jacket carries a 5V/3A, 12V/5A power bank. I assume this ought to be enough?
• What screen type can I use? Amazon has a few options I'm considering, like this, this, and this.
• How do I... Do it? If you can point me to a tutorial, that'd be awesome!

What I have:

• I'm a software engineer by trade, so need little handholding. Just need a rough outline of steps and I should be able to figure it out from there!
• I plan to 3D-print a chassis to hold everything.
• I've got a soldering iron, multimeter, the works. I'm ready to go, just need a shopping list!

Thank you so much!
