4 open source boards using the 4052
Real designs built with the 4052, 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.

Microcontrollers on boards using the 4052
What boards using the 4052 are built for
4052: common questions
Where can I find a 4052 reference design?
Each of the 4 boards on this page is a real design using the 4052. 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 4052 use?
Most are built on PIC (1), RP2040/RP2350 (1) and STM32 (1).
How big is a typical board using the 4052?
The median is 109.5 × 88.5 mm, and 100% are two-layer designs.
What is the most popular open source board using the 4052?
By GitHub stars, NES backup by digilogistist, with 24 stars.
Can I simulate one of these boards using the 4052 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.
