Which microcontrollers do boards using the TCA9801 use?

Most are built on STM32 (1).

How big is a typical board using the TCA9801?

The median is 87.5 × 75.7 mm, and 0% are two-layer designs.

What is the most popular open source board using the TCA9801?

By GitHub stars, Quasar Backplane by petrinm, with 6 stars.

Can I simulate one of these boards using the TCA9801 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.
