The Lonely Binary VGA ESP32 Shield utilizes the ESP32's I²S peripheral, originally designed for audio, to output VGA video with precise timing for RGB color data synchronization.
Two models are available: the 3-Bit VGA Shield, which uses 5 digital GPIO pins and less memory, making it suitable for text output and projects requiring additional device connections; and the 14-Bit VGA Shield, which uses 16 GPIO pins and more memory, ideal for graphics-intensive applications and vivid color displays but with fewer available GPIOs.
These shields are versatile for various applications, from educational tools to digital signage, especially when VGA output is needed on larger screens.
