Most are built on AVR/Arduino (2).

How big is a typical board using the 7805_N?

The median is 100 × 82 mm, and 100% are two-layer designs.

What is the most popular open source board using the 7805_N?

By GitHub stars, ProgrammableRelayModule4Channel by numato, with 143 stars.

Can I simulate one of these boards using the 7805_N 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.
