In reality, the image quality is better, but this is difficult to convey in photographs.
In February of this year, the ST7789 display module arrived to me; the quality of the picture and colors, despite the small size, was impressive, so one idea came to my mind …
Maybe develop a keychain that you can play Pokemon on?
At this point, the primitive idea of microByte was born. More than seven months later, the key fob idea has evolved into a fully functional handheld console capable of emulating:
- Gameboy color
- Sega Master System
On the other hand, you may be wondering why add an SNES gamepad layout (directional buttons, 4 action buttons, Start, Select, L and R) when the device can only emulate 8-bit games?
Well, yes, so far it is only capable of running 8-bit games, but after doing a thorough search, I found out that the first ports of the SNES and SCRUMV emulator already exist for ESP32. Therefore, it became obvious that the device requires a full layout of the SNES gamepad with the prospect of further updates.
In addition, I believe that apart from games, the device can be a very useful tool in developing projects with ESP32, because it is possible to run Arduino sketches and / or binary files of ESP-IDF projects from an SD card as an application without removing the main firmware. … Below I will tell you more about this.
Here’s a quick video overview:
