FST3253: common questions

Where can I find a FST3253 reference design?

Each of the 7 boards on this page is a real design using the FST3253. Open one to see how it is wired up, with the full BOM, a render of the layout and links to its KiCad files.

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.
