Which microcontrollers do boards using the FE8.1 use?
Most are built on RP2040/RP2350 (1).
How big is a typical board using the FE8.1?
The median is 43.4 × 18.8 mm, and 100% are two-layer designs.
What is the most popular open source board using the FE8.1?
By GitHub stars, Usb sniffer lite by ataradov, with 701 stars.
Can I simulate one of these boards using the FE8.1 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.
