From the project

ESP32 based project with addressable LED displays, simulating basic CPU architecture with website Websocket connectivity for real time visualization

This project is a software implementation for hosting an Access Point and Web Server on ESP32 microcontroller. It features WebSocket communication, DNS Capture Portal, and LED control.

- ESP32 microcontroller - ESP32 development environment (e.g., Arduino IDE, PlatformIO) - Web browser for accessing the user interface

2. Set up the ESP32 development environment (PlatformIO recomended). 3. Upload the website build to the ESP32.

Main board esp32: common questions

What microcontroller does the Main board esp32 use?

The Main board esp32 is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Main board esp32?

The Main board esp32 measures 164.3 × 145 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Main board esp32?

77 components, from 27 distinct parts. The full bill of materials is listed on this page.

Where can I download the Main board esp32 design files?

From the MrRooby/Maszyna-W-ESP32 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Main board esp32 design in my own project?

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

Can I test firmware for the Main board esp32 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.
