Which microcontrollers do boards using the WM8731 use?
Most are built on STM32 (2).
How big is a typical board using the WM8731?
The median is 76.2 × 76.2 mm, and 67% are two-layer designs.
What is the most popular open source board using the WM8731?
By GitHub stars, Guitarboard by JonasNorling, with 97 stars.
Can I simulate one of these boards using the WM8731 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.
