Which microcontrollers do boards using the C81720 use?
Most are built on STM32 (2).
How big is a typical board using the C81720?
The median is 199.5 × 81 mm, and 100% are two-layer designs.
What is the most popular open source board using the C81720?
By GitHub stars, Pdk prog by brainsmoke, with 1 stars.
Can I simulate one of these boards using the C81720 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.
