Which microcontrollers do boards using the HT16K33 use?

Most are built on AVR/Arduino (1) and ESP32 (1).

How big is a typical board using the HT16K33?

The median is 316.6 × 235.9 mm, and 100% are two-layer designs.

What is the most popular open source board using the HT16K33?

By GitHub stars, Dash-PCB by sufst, with 19 stars.

Can I simulate one of these boards using the HT16K33 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.
