KiCad project files for a custom ESP32 development board

The board features a simplistic design, breaking out GPIO and power pins for easy prototyping, while using only essential components for power and data transfer.

KiCad project files include the schematic and PCB designs which can be viewed and edited, and a full BOM with LCSC part numbers for sourcing and assembly.

Core: ESP32-S3-WROOM-1N8R8 module (8MB Flash + 8MB PSRAM). USB Interface: USB-C connector utilizing the S3's native USB Serial/JTAG controller. Power: Integrated 3.3V LDO regulator with a dedicated power LED indicator. Prototyping: Standard 2.54mm pitch header pins for full GPIO…

Esp32-dev board: common questions

What microcontroller does the Esp32-dev board use?

The Esp32-dev board is built around the AP2114H-3.3, from the ESP32 family.

How big is the Esp32-dev board?

The Esp32-dev board measures 47.2 × 29 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32-dev board?

18 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esp32-dev board design files?

From the rhammell/esp32-dev-board 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-dev board design in my own project?

Yes, under the terms of its GPL-3.0 license, which rhammell chose for the repository.

Can I test firmware for the Esp32-dev 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.
