uA7805: common questions

Where can I find a uA7805 reference design?

Each of the 3 boards on this page is a real design using the uA7805. 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 uA7805 use?

Most are built on AVR/Arduino (1), ESP32 (1) and PIC (1).

How big is a typical board using the uA7805?

The median is 140 × 60 mm, and 100% are two-layer designs.

What is the most popular open source board using the uA7805?

By GitHub stars, Smu main 1 by jaromir-sukuba, with 188 stars.

Can I simulate one of these boards using the uA7805 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.
