Which microcontrollers do boards using the ttp223 use?

Most are built on AVR/Arduino (1).

How big is a typical board using the ttp223?

The median is 55.7 × 82.8 mm, and 100% are two-layer designs.

What is the most popular open source board using the ttp223?

By GitHub stars, OpenThereminV4 by GaudiLabs, with 238 stars.

Can I simulate one of these boards using the ttp223 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.
