About the ESP32-Faikout-CostOptimize PCB

ESP32-Faikout-CostOptimize is an open source ESP32 PCB design by Phiumi, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 70 × 58 mm, with 23 components from 14 distinct parts.

Its main chip is the ESP32-S3-MINI-1, from the ESP32 family. Other key parts include the MPM3632CGQV-Z. By type, the board carries 9 capacitors, 6 resistors, 3 diodes, 2 ICs, 2 transistors and 1 connector.

From the project

This is a cost optimize version of the original repo by RevK

This repository contains a hardware redesign of the ESP32-Faikout, originally created by RevK.

This project is specifically optimized for JLC-PCB PCBA (Assembly service). The PCB dimensions are slightly larger, see the measurements below.

This version introduces several technical optimizations to lower costs and improve manufacturing reliability:

Streamlined BOM: The Bill of Materials has been reduced from 17 lines to 13 lines, minimizing component variety and simplifying the assembly process. JLC "Basic" Parts: Wherever possible, I have selected parts from the JLC Basic Library. 4-Layer…

What microcontroller does the ESP32-Faikout-CostOptimize use?

The ESP32-Faikout-CostOptimize is built around the ESP32-S3-MINI-1, from the ESP32 family.

How big is the ESP32-Faikout-CostOptimize PCB?

The ESP32-Faikout-CostOptimize measures 70 × 58 mm, has 4 copper layers and is 1.5842 mm thick.

How many components are on the ESP32-Faikout-CostOptimize?

23 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the ESP32-Faikout-CostOptimize design files?

From the Phiumi/ESP32-Faikout-CostOptimize 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-Faikout-CostOptimize design in my own project?

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

Can I test firmware for the ESP32-Faikout-CostOptimize 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.
