Which microcontrollers do boards using the FT231XS-U use?
Most are built on AVR/Arduino (1).
How big is a typical board using the FT231XS-U?
The median is 43.5 × 36 mm, and 100% are two-layer designs.
What is the most popular open source board using the FT231XS-U?
By GitHub stars, PCB D by dragondgold, with 5 stars.
Can I simulate one of these boards using the FT231XS-U 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.
