About the Esp32 PCB

Esp32 is an open source ESP32 PCB design by aguscsc, published on GitHub under the MIT license. It is a 2-layer board measuring 62 × 28.5 mm, with 19 components from 14 distinct parts.

Its main chip is the ESP32-C3-WROOM-02, from the ESP32 family. Other key parts include the AMS1117-3.3. By type, the board carries 9 resistors, 4 capacitors, 3 connectors, 2 ICs and 1 switch.

It belongs with the power & battery and test & measurement designs in this gallery.

From the project

This repository contains the development steps for the making of a Bidirectional Buck DC-DC converter

This repository documents the design and implementation of a bidirectional DC-DC converter. The system can operate in both buck mode (step-down) and boost mode (step-up), enabling power flow in both directions.

Esp32: common questions

What microcontroller does the Esp32 use?

The Esp32 is built around the ESP32-C3-WROOM-02, from the ESP32 family.

How big is the Esp32 PCB?

The Esp32 measures 62 × 28.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32?

19 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esp32 design files?

From the aguscsc/Bidirectional-Buck-DC-DC-converter 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 design in my own project?

Yes, under the terms of its MIT license, which aguscsc chose for the repository.

Can I test firmware for the 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.
