About the Fence esp32 PCB

Fence esp32 is an open source ESP32 PCB design by floitsch, published on GitHub under the MIT license. It is a 2-layer board measuring 76.2 × 44 mm, with 57 components from 19 distinct parts.

Its main chip is the ESP32-C3-MINI-1, from the ESP32 family. Other key parts include the CH32X035C8T6, AMS1117-3.3, CH446Q and TPS60401DBV. By type, the board carries 27 resistors, 14 capacitors, 6 ICs, 6 connectors, 2 diodes and 1 jumper.

From the project

Research project for coupled, autonomous PCB placement and routing (Rust, KiCad-gated)

These boards come from a separate hardware project, the "breadboard fence" in ~/programming/breadboard-enhancer/hw/ (generator fence.toit, written in Toit; the finished boards are in its kicad/). That project uses pcb-maker as its placer and router and never patches it. Instead, everything pcb-maker got wrong, or could not express, is logged here together with the boards that show it.

Fence esp32: common questions

What microcontroller does the Fence esp32 use?

The Fence esp32 is built around the ESP32-C3-MINI-1, from the ESP32 family.

How big is the Fence esp32 PCB?

The Fence esp32 measures 76.2 × 44 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Fence esp32?

57 components, from 19 distinct parts. The full bill of materials is listed on this page.

Where can I download the Fence esp32 design files?

From the floitsch/pcb-maker repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Fence esp32 design in my own project?

Yes, under the terms of its MIT license, which floitsch chose for the repository.

Can I test firmware for the Fence esp32 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.
