Which microcontrollers do boards using the TL331 use?
Most are built on PIC (1).
How big is a typical board using the TL331?
The median is 143.8 × 74.2 mm, and 50% are two-layer designs.
What is the most popular open source board using the TL331?
By GitHub stars, MTouch Test by drewsum, with 2 stars.
Can I simulate one of these boards using the TL331 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.
