Which microcontrollers do boards using the L76-M33 use?
Most are built on STM32 (3).
How big is a typical board using the L76-M33?
The median is 68 × 33.5 mm, and 50% are two-layer designs.
What is the most popular open source board using the L76-M33?
By GitHub stars, Transponder-12.0.1 by peterantypas, with 444 stars.
Can I simulate one of these boards using the L76-M33 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.
