MCU-ESP32S3-MINI
About the MCU-ESP32S3-MINI PCB
MCU-ESP32S3-MINI is an open source ESP32 PCB design by AnotherMike-exe, published on GitHub under the MIT license. It is a 4-layer board measuring 27 × 24 mm, with 11 components from 8 distinct parts.
Its main chip is the ESP32-S3-MINI-1-N8, from the ESP32 family. By type, the board carries 4 capacitors, 4 resistors, 2 switches and 1 IC.
From the project
Reusable KiCad 10 PCB layout blocks: module reference boards, design block fragments and host setup docs
Reusable PCB layout blocks for Plum Solutions boards. Nine schematic design blocks exist. Each one gets a matching layout so a host project can drop in the parts, the routing and the copper pours already proven on a reference board.
The fragment lives outside this repository, in the shared library on the Plum volume. See docs/ARCHITECTURE.md.
PoE-PD-Si3402-Class1 is retired. PoE always arrives on an Ethernet cable, so a PoE block with no jack was never a drop-in part.

MCU-ESP32S3-MINI: common questions
What microcontroller does the MCU-ESP32S3-MINI use?
The MCU-ESP32S3-MINI is built around the ESP32-S3-MINI-1-N8, from the ESP32 family.
How big is the MCU-ESP32S3-MINI PCB?
The MCU-ESP32S3-MINI measures 27 × 24 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the MCU-ESP32S3-MINI?
11 components, from 8 distinct parts. The full bill of materials is listed on this page.
Where can I download the MCU-ESP32S3-MINI design files?
From the AnotherMike-exe/KiCadBlocks repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the MCU-ESP32S3-MINI design in my own project?
Yes, under the terms of its MIT license, which AnotherMike-exe chose for the repository.
Can I test firmware for the MCU-ESP32S3-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.
