Which microcontrollers do boards using the CN3085 use?
Most are built on ESP32 (1) and STM32 (1).
How big is a typical board using the CN3085?
The median is 88 × 40 mm, and 50% are two-layer designs.
What is the most popular open source board using the CN3085?
By GitHub stars, Stm8-car ctrl by akrapivniy, with 6 stars.
Can I simulate one of these boards using the CN3085 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.
