Which microcontrollers do boards using the MDBT40 use?

Most are built on Nordic nRF (3).

How big is a typical board using the MDBT40?

The median is 285 × 94.6 mm, and 100% are two-layer designs.

What is the most popular open source board using the MDBT40?

By GitHub stars, Jalapeno by GeeWizWow, with 13 stars.

Can I simulate one of these boards using the MDBT40 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.
