Which microcontrollers do boards using the FST3253 use?
Most are built on AVR/Arduino (3) and RP2040/RP2350 (1).
How big is a typical board using the FST3253?
The median is 80.3 × 56 mm, and 100% are two-layer designs.
What is the most popular open source board using the FST3253?
By GitHub stars, IQ SDR by frohro, with 10 stars.
Can I simulate one of these boards using the FST3253 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.
