3 open source boards using the piezo
Real designs built with the piezo, 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.

What boards using the piezo are built for
piezo: common questions
Where can I find a piezo reference design?
Each of the 3 boards on this page is a real design using the piezo. 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 piezo use?
Most are built on STM32 (2) and ESP32 (1).
How big is a typical board using the piezo?
The median is 78.7 × 53.8 mm, and 67% are two-layer designs.
What is the most popular open source board using the piezo?
By GitHub stars, ControlBoard by paradise-fi, with 42 stars.
Can I simulate one of these boards using the piezo 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.
