Its main chip is the ESP32-S3-MINI-1, from the ESP32 family. Other key parts include the LD1117S33TR and CP2102N-QFN24. By type, the board carries 14 diodes, 11 capacitors, 11 resistors, 4 connectors, 3 ICs and 2 transistors.

It belongs with the iot & wireless, dev boards & breakouts and usb & debug tools designs in this gallery.

From the project

A 4-layer dev board around the ESP32-S3-MINI-1 with dual USB-C ports

A professional-grade, high-performance ESP32-S3 Development Board. This hardware implementation uses a 4-layer PCB stackup to optimize signal integrity, accommodate controlled-impedance differential USB paths, and provide a low-noise ground reference for the RF module's wireless performance.

Traces assigned to USBOTG and USBUART lines are routed as 90Ω differential pairs**.

ESP32-S3-Dev-Board: common questions

What microcontroller does the ESP32-S3-Dev-Board use?

The ESP32-S3-Dev-Board is built around the ESP32-S3-MINI-1, from the ESP32 family.

How big is the ESP32-S3-Dev-Board?

The ESP32-S3-Dev-Board measures 70.1 × 26.6 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the ESP32-S3-Dev-Board?

48 components, from 23 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-S3-Dev-Board design files?

From the Vibhors-Tech-Hub/ESP32-S3-Dev-Board 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-S3-Dev-Board design in my own project?

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

Can I test firmware for the ESP32-S3-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.
