About the Esp32s3-devkit PCB

Esp32s3-devkit is an open source ESP32 PCB design by eshelton328, published on GitHub. It is a 4-layer board measuring 59.3 × 38 mm, with 36 components from 22 distinct parts.

Its main chip is the ESP32-S3-WROOM-1-N16, from the ESP32 family. Other key parts include the TPS63070RNMR and USBLC6-2SC6. By type, the board carries 12 capacitors, 11 resistors, 3 ICs, 3 connectors, 3 switches and 2 diodes.

It belongs with the iot & wireless, power & battery and dev boards & breakouts designs in this gallery.

From the project

Hardware design monorepo with software-grade CI/CD. KiCad PCB projects with automated ERC/DRC, multi-fab rule validation, schematic & BOM checks, and auto-generated board documentation.

Development board built around the ESP32-S3-WROOM-1 module with an integrated TPS63070 buck-boost converter and USB-C connectivity.

- MCU: ESP32-S3-WROOM-1 (Wi-Fi + BLE, dual-core, 32-bit) - Power: battery only — 3×AA (≈3.0–4.8 V) on the VBAT header pin, through reverse-polarity PFET (Q1) and power switch (SW1) into a TPS63070 buck-boost (3.3 V regulated output) - Interface: USB-C (USB 2.0, 16-pin receptacle) — data only, by design; VBUS does not power the board. Batteries must be connected and SW1 on to flash. - ESD protection: USBLC6-2SC6 on USB data lines - Layers: 4 - Thickness: 1.6mm -…

Esp32s3-devkit: common questions

What microcontroller does the Esp32s3-devkit use?

The Esp32s3-devkit is built around the ESP32-S3-WROOM-1-N16, from the ESP32 family.

How big is the Esp32s3-devkit PCB?

The Esp32s3-devkit measures 59.3 × 38 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Esp32s3-devkit?

36 components, from 22 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 Esp32s3-devkit design files?

From the eshelton328/the-forge 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 Esp32s3-devkit design in my own project?

The repository has no license, so all rights stay with eshelton328. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Esp32s3-devkit 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.
