Which microcontrollers do boards using the PCA9306DCUR use?
Most are built on ESP32 (1) and STM32 (1).
How big is a typical board using the PCA9306DCUR?
The median is 80 × 80 mm, and 33% are two-layer designs.
What is the most popular open source board using the PCA9306DCUR?
By GitHub stars, RC14 by AgOpenGPS-Official, with 20 stars.
Can I simulate one of these boards using the PCA9306DCUR 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.
