I created another device—just to simulate the 3.5 LCD display I found on AliExpress. After doing some research and looking at other options, I decided against using Seeed’s S3 Sense. It comes with an OV2640 camera, but I’m going to use an external OV5640 module instead—a 5MP one I bought along with the other two.

I did some research, checked out components and versions in the LCSC library, verified a few things with Perplexity, and added the items to the schematic. It’s still pretty messy, but I’ll clean it up, organize it, and get the NET’s sorted out later.
