From the project

VGA ESP32-S3 Breakout board for WROOM1- DevKit

Implementing a discrete DAC R-2R allows for full control over the signal chain and demonstrates the ability to interface digital MCUs with legacy analog standards without relying on specialized external ICs

Colors are encoded as unsigned 16bits integer (B5G6R5).

The five (5) lowest bits are red and in accending order of brigtness. The next six (6) bits are green and the last five (5) bits are blue.

The ESP32-S3-VGA-ADAPTOR is built around the ESP32-S3-DEVKITC-1-N8R2, from the ESP32 family.

How big is the ESP32-S3-VGA-ADAPTOR PCB?

The ESP32-S3-VGA-ADAPTOR measures 100 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32-S3-VGA-ADAPTOR?

31 components, from 15 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP32-S3-VGA-ADAPTOR design files?

From the cfrankb/ESP32-S3-VGA-ADAPTOR repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ESP32-S3-VGA-ADAPTOR design in my own project?

The repository has no license, so all rights stay with cfrankb. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the ESP32-S3-VGA-ADAPTOR without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
