Microcontrollers on boards using the PUSB3FR4Z
What boards using the PUSB3FR4Z are built for
PUSB3FR4Z: common questions
Where can I find a PUSB3FR4Z reference design?
Each of the 12 boards on this page is a real design using the PUSB3FR4Z. 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 PUSB3FR4Z use?
Most are built on STM32 (12).
How big is a typical board using the PUSB3FR4Z?
The median is 246.5 × 200 mm, and 0% are two-layer designs.
What is the most popular open source board using the PUSB3FR4Z?
By GitHub stars, Quantum control by embeddedos-org, with 8 stars.
Can I simulate one of these boards using the PUSB3FR4Z 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.
