6 open source boards using the ESP32
Real designs built with the ESP32, from public GitHub projects: a quick way to see how others power, decouple and connect it. Each board comes with its KiCad files, full parts list and a render — and you can simulate its firmware on HardLabs.

ESP32: common questions
Where can I find a ESP32 reference design?
Each of the 6 boards on this page is a real design using the ESP32. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.
Which microcontrollers do boards using the ESP32 use?
Most are built on ESP32 (5) and RP2040/RP2350 (1).
How big is a typical board using the ESP32?
The median is 62.9 × 52 mm, and 83% are two-layer designs.
What is the most popular open source board using the ESP32?
By GitHub stars, L0 ESP32 by Luos-io, with 547 stars.
Can I simulate one of these boards using the ESP32 before building it?
Yes. HardLabs turns a board's netlist and BOM into a working simulation, so you can boot and test firmware against it with no hardware on your desk.
