About the Test backup PCB

Test backup is an open source ESP32 PCB design by himanshu40304, published on GitHub. It is a 2-layer board measuring 100 × 30 mm, with 30 components from 22 distinct parts.

Its main chip is the ESP32-C3-WROOM-02, from the ESP32 family. Other key parts include the HLK-5M05 and AMS1117-3.3. By type, the board carries 9 capacitors, 6 resistors, 3 ICs, 2 connectors, 2 switches and 2 LEDs.

It belongs with the iot & wireless designs in this gallery.

From the project

This repository contains the automation workflow and some projects made by using this workflow which makes pcb designs using ai assistance faster than making pcb designs manually.

An autonomous, end-to-end PCB design, verification, and manufacturing pipeline powered by KiCad 10, SPICE, OpenEMS 3D FDTD, ParaView, and AI-driven Automation Agents.

⭐ If you find this repository useful for your PCB workflows or research, please consider giving it a star!

This repository contains automated workflows, design tools, and complete hardware projects demonstrating AI-assisted schematic creation, SPICE verification, electrical rules check (ERC), automated component placement, routing, clearance isolation, and design rules check (DRC).

Test backup: common questions

What microcontroller does the Test backup use?

The Test backup is built around the ESP32-C3-WROOM-02, from the ESP32 family.

How big is the Test backup PCB?

The Test backup measures 100 × 30 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Test backup?

30 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 Test backup design files?

From the himanshu40304/PCB_automation repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Test backup design in my own project?

The repository has no license, so all rights stay with himanshu40304. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Test backup 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.
