ESP-NES
Rediscover the golden age of 8-bit gaming with Anemoia! This project is a custom-designed, all-in-one PCB that transforms a powerful ESP32 microcontroller into a fully functional Nintendo Entertainment System (NES) emulator, powered by the open-source code from the Anemoia-ESP32 GitHub repository. Built from the ground up to be a portable, high-performance retro console, Anemoia lets you play your favorite classic games anywhere, anytime. Repo link https://github.com/Shim06/Anemoia-ESP32

Your project still includes AI in the readme, and I have a feeling your PCB speaker doesn't work, please get that double checked!

first version of the ESP-NES PCB is complete
This has been very hard and fun, but the first version of the ESP-NES PCB is officially designed. I've spent a total of 8 hours on this over the last several days, and it's finally complete.
Along with the board layout, I've generated the full Bill of Materials (BOM) as a CSV file and I also Public all files like schematics,pcb and more
A large chunk of that time was spent just learning the fundamentals of PCB design. It's a steep learning curve, and I had to go back and update the schematics multiple times as I discovered better ways to route traces or place components.
It was a challenging process, but splitting the work up made it manageable. Seeing the final, completed board layout after all that effort feels like a huge accomplishment. Next step: ordering the parts and the board itself!

Start making PCB of esp-nes
Okay, so I'm trying to make a real PCB for my ESP-NES project.
Honestly, I went into this knowing absolutely nothing. The design software looked so intimidating, and for a while, I just stared at the screen. After diving into a bunch of tutorials, I finally got the courage to just... start.
I dropped the ESP32 chip in the middle, placed the buttons where they felt right, and then began the crazy puzzle of connecting all the tiny lines. This is my first real attempt. It's probably got a dozen mistakes, but it's actually starting to look like a real circuit board! Seeing this on my screen instead of a jumble of wires is an awesome feeling. A small step, but I'm proud of it.

ESP-NES schematics
The schematic for my custom ESP-NES is finally done! It feels great to have the complete electronic blueprint finalized on a single sheet.
The design is centered on an ESP32, connecting it to a display that conveniently has an SD card slot built-in, which really simplifies the wiring. I've also mapped out the PAM8403 audio amplifier and all eight of the tactile buttons for the controls.
With the logic and connections all laid out, the next and most exciting step is designing the physical PCB layout. It's time to bring this thing to life!
