NRSC-5 is a high-definition radio standard, used primarily in the United States. It allows for digital and analog transmissions to share the original FM bandwidth allocations.

He put it all together on proto-board, although soldering the FM radio module was a bit tricky. The Arduino code is quite simple, and available for download (zip file).

In a 3 x 3 x 0.55 mm package, the tuners require a reduced PCB area of 10 mm square, a reduction of 75 percent compared to competitive offerings. Typical applications include cellular phones, ...

You do. Every smartphone in the world has an FM tuner built in. But here in the US, just one-third of them actually works, even though the Federal Emergency Management Agency says radio can save ...

Most smartphones have a built-in FM chip. But whether or not it's activated is in the hands of the mobile carriers, who profit when you stream radio. The broadcast industry is pushing to change this.

The PCB layout supports multi-layer boards (up to 30 layers), as well as DRC. There is not yet an autoplacer, but this is high priority on the company’s roadmap, as is an autorouter.
