๐ฎ Building a DIY Gaming Console Using ESP32
Retro games never get old.
As makers and embedded developers, we usually build IoT dashboards, sensor projects, automation systems, and robots. But this time I wanted to build something different:
A mini gaming console powered by ESP32.
The goal was simple:
โ Build with low-cost components
โ Add multiple games
โ Use an OLED display
โ Keep it open source
โ Make it easy for anyone to recreate
The result is a compact DIY gaming console capable of running classic games directly from an ESP32 development board.
