About the Esp32-board

Esp32-board is an open source ESP32 PCB design by danielkurek, published on GitHub. It is a 2-layer board measuring 41.5 × 70.3 mm, with 41 components from 25 distinct parts.

Its main chip is the ESP32-S3-WROOM-1, from the ESP32 family. Other key parts include the NCP186-3V3. By type, the board carries 10 resistors, 9 capacitors, 6 diodes, 5 connectors, 3 transistors and 3 jumpers.

From the project

Boards were designed in KiCAD 7 (then converted to KiCAD 8). In folders esp32-s3-main and esp32-s3-simple are source files for boards along with exported schematics to PDF, exported BOM and gerbers ready for manufacturing.

Esp32-board: common questions

What microcontroller does the Esp32-board use?

The Esp32-board is built around the ESP32-S3-WROOM-1, from the ESP32 family.

How big is the Esp32-board?

The Esp32-board measures 41.5 × 70.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32-board?

41 components, from 25 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-board design files?

From the danielkurek/imf 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-board design in my own project?

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

Can I test firmware for the Esp32-board 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.
