Which microcontrollers do boards using the ST485 use?
Most are built on PIC (2) and ESP32 (1).
How big is a typical board using the ST485?
The median is 99.5 × 99.5 mm, and 100% are two-layer designs.
What is the most popular open source board using the ST485?
By GitHub stars, Balancer by kwiecinski, with 3 stars.
Can I simulate one of these boards using the ST485 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.
