Which microcontrollers do boards using the C39051 use?

Most are built on RP2040/RP2350 (2) and ESP32 (1).

How big is a typical board using the C39051?

The median is 30 × 51 mm, and 100% are two-layer designs.

What is the most popular open source board using the C39051?

By GitHub stars, Cinread-IT8951 S3 HAT by martinberlin, with 12 stars.

Can I simulate one of these boards using the C39051 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.
