Which microcontrollers do boards using the MOC3021 use?
Most are built on ESP32 (1).
How big is a typical board using the MOC3021?
The median is 114.3 × 86.8 mm, and 100% are two-layer designs.
What is the most popular open source board using the MOC3021?
By GitHub stars, Clean room slave by trieuhuyduc, with 1 stars.
Can I simulate one of these boards using the MOC3021 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.
