Which microcontrollers do boards using the 3V3-LDO use?
Most are built on ESP32 (3).
How big is a typical board using the 3V3-LDO?
The median is 87 × 154 mm, and 100% are two-layer designs.
What is the most popular open source board using the 3V3-LDO?
By GitHub stars, PistormTester by abrugsch, with 11 stars.
Can I simulate one of these boards using the 3V3-LDO 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.
