About the Esp32s2-funprog PCB

Esp32s2-funprog is an open source ESP32 PCB design by cnlohr, published on GitHub under the MIT license. It is a 2-layer board measuring 22 × 56 mm, with 71 components from 30 distinct parts.

Its main chip is the ESP32-S2, from the ESP32 family. Other key parts include the XC6206P332, MT3608, COSNE5532, AT8837 and ANT. By type, the board carries 25 resistors, 24 capacitors, 8 ICs, 3 transistors, 3 connectors and 3 diodes.

From the project

My dumping grounds for all my kicad projects and random hardware bringup.

NOTE FOR PULL REQUESTS: I DO NOT ACCEPT MASS ADDS. If you have 5-6 really awesome parts, I'll accept a pull request, but if you have say 10+ parts, I will not. Select only the neatest. Also, make sure JLCPCB offers the parts, if they're intended for board mounting!

Esp32s2-funprog: common questions

What microcontroller does the Esp32s2-funprog use?

The Esp32s2-funprog is built around the ESP32-S2, from the ESP32 family.

How big is the Esp32s2-funprog PCB?

The Esp32s2-funprog measures 22 × 56 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Esp32s2-funprog?

71 components, from 30 distinct parts. The full bill of materials is listed on this page.

Where can I download the Esp32s2-funprog design files?

From the cnlohr/cnhardware repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Esp32s2-funprog design in my own project?

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

Can I test firmware for the Esp32s2-funprog 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.
