Which microcontrollers do boards using the Si3404 use?
Most are built on ESP32 (2).
How big is a typical board using the Si3404?
The median is 25.3 × 61 mm, and 67% are two-layer designs.
What is the most popular open source board using the Si3404?
By GitHub stars, LAN-Module-PoE-Castellated by jorticus, with 8 stars.
Can I simulate one of these boards using the Si3404 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.
