Which microcontrollers do boards using the HT7550 use?

Most are built on STM32 (2).

How big is a typical board using the HT7550?

The median is 52.7 × 40.2 mm, and 0% are two-layer designs.

What is the most popular open source board using the HT7550?

By GitHub stars, F405 pill by davidmolony, with 21 stars.

Can I simulate one of these boards using the HT7550 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.
