Which microcontrollers do boards using the TL431 use?
Most are built on NXP (2).
How big is a typical board using the TL431?
The median is 99.4 × 78.4 mm, and 88% are two-layer designs.
What is the most popular open source board using the TL431?
By GitHub stars, UVerter by owntech-foundation, with 112 stars.
Can I simulate one of these boards using the TL431 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.
