Which microcontrollers do boards using the CH340K use?

Most are built on ESP32 (1).

How big is a typical board using the CH340K?

The median is 90 × 56.5 mm, and 100% are two-layer designs.

What is the most popular open source board using the CH340K?

By GitHub stars, SensactHsNano2 by klaus-liebler, with 4 stars.

Can I simulate one of these boards using the CH340K 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.
