The ESP32 series from Espressif have been a successful line of products, offering a powerful microcontroller with on-chip wireless networking. There’s a snag though in their practice of calling all of ...

In a world where standards come and go with alarming speed, there’s something comforting about VGA. It’s the least common denominator of video standards, and seeing that chunky DB15 connector on the ...

The VGA output has 2 bits per color channel (which results in an image of 64 colors). I use some very simple homemade DACs built with a few resistors on a perfboard, but there are people around ...

Ivan Svarkovsky’s S3-MSX-PC open-source project implements a bare-metal MSX2+ emulator running on an ESP32-S3 microcontroller and outputting 64-color VGA via a simple R-2R resistor ladder. It’s a fork ...

Hackaday After reading the article "Deeply Optimized MSX Emulation On ESP32-S3 With VGA Output," I felt that the meticulous optimization techniques for emulating retro PCs on small microcontrollers ...

M5Stack ATOMS3R and ATOMS3R Cam are two tiny devkits based on ESP32-S3-Pico system-in-package and a similar design but the first one features a 0.85-inch color color IPS display, while the other is ...
