About the ESP32 4Layer PCB

ESP32 4Layer is an open source ESP32 PCB design by anshukumar146, published on GitHub. It is a 4-layer board measuring 39.9 × 58.5 mm, with 34 components from 18 distinct parts.

Its main chip is the 8051, from the ESP32 family. Other key parts include the AMS1117-3.3 and BMP280. By type, the board carries 10 capacitors, 7 resistors, 6 diodes, 5 ICs, 4 switches and 2 connectors.

It belongs with the iot & wireless, displays & leds and sensors designs in this gallery.

From the project

A 4-layer ESP32-S3 development board built as a standalone weather station — combining a Wi-Fi/BLE MCU, a TFT display, and a set of environmental sensors (temperature/humidity, barometric pressure, and ambient light/UV) into a single self-contained PCB, designed in KiCad.

Purpose This repository contains the full KiCad design (schematic, PCB layout, and fabrication outputs) for a 4-layer ESP32-S3 weather station board. It's built around the ESP32-S3-WROOM-1 module and integrates a TFT display, temperature/humidity sensing, barometric pressure sensing, and ambient light sensing on a single…

ESP32 4Layer: common questions

What microcontroller does the ESP32 4Layer use?

The ESP32 4Layer is built around the 8051, from the ESP32 family.

How big is the ESP32 4Layer PCB?

The ESP32 4Layer measures 39.9 × 58.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ESP32 4Layer?

34 components, from 18 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the ESP32 4Layer design files?

From the anshukumar146/GitHub repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the ESP32 4Layer design in my own project?

The repository has no license, so all rights stay with anshukumar146. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the ESP32 4Layer 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.
