About the ESP32S3-DEVKIT-MINI PCB

ESP32S3-DEVKIT-MINI is an open source ESP32 PCB design by Zektopic, published on GitHub. It is a 2-layer board measuring 25.4 × 68.6 mm, with 45 components from 17 distinct parts.

Its main chip is the ESP32-S3-MINI-1-N8, from the ESP32 family. Other key parts include the CP2102N-Axx-xQFN28 and SGM2212-3.3XKC3G/TR. By type, the board carries 15 resistors, 12 capacitors, 6 diodes, 5 connectors, 3 ICs and 2 transistors.

From the project

ESP32-S3 DevKIT Made using the Espressif Schematics, Needs more changes and improvements , donot hesitate to make changes and suggest improvements. Final Plan is to implemnt a global datalogger

To do: Implement USB Add seperate i2c and spi as connectors to connect to modules - Check my datalogger project Add Silkscreen things - Need to do Improve routing and make it prettier

ESP32S3-DEVKIT-MINI: common questions

What microcontroller does the ESP32S3-DEVKIT-MINI use?

The ESP32S3-DEVKIT-MINI is built around the ESP32-S3-MINI-1-N8, from the ESP32 family.

How big is the ESP32S3-DEVKIT-MINI PCB?

The ESP32S3-DEVKIT-MINI measures 25.4 × 68.6 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the ESP32S3-DEVKIT-MINI?

45 components, from 17 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP32S3-DEVKIT-MINI design files?

From the Zektopic/ESP32S3-DEVKIT-MINI repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the ESP32S3-DEVKIT-MINI design in my own project?

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

Can I test firmware for the ESP32S3-DEVKIT-MINI 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.
