Which microcontrollers do boards using the LM809 use?

Most are built on ESP32 (1).

How big is a typical board using the LM809?

The median is 68 × 65.6 mm, and 100% are two-layer designs.

What is the most popular open source board using the LM809?

By GitHub stars, ULTRATERM PCB by jamdotjar, with 8 stars.

Can I simulate one of these boards using the LM809 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.
