    This is the same chip used in the Tecsun PL390. (Nearly the same, PL390 uses SI4734, same as SI4735 without RDS/RBDS.)
    I’ve been quite impressed with its performance on shortwave. Just connect a whip antenna or a length of wire and tune the shortwave bands.
    Limitations include 1 kHz tuning resolution, the I/Q outputs aren’t accessible, no SSB or CW, just AM.

    Everyone, it’s just a breakout - nothing stopping you from connecting it to anything, not just Arduinos.

    Yay! I’ve been looking for little meters, they’ve gotten hard to find! LEDs are great, but nothing beats the swinging needle for that dynamic pulse. The 5V meter is just right to drive with an Arduino PWM pin, using analogWrite(). Looks like it can be opened up to put in a custom laser-printed scale. (Who will post a template?) We do need to know the sensitivity in ohms per volt. Thanks!

    Question, what’s the resolution? In a shaft encoder it would be steps per revolution. Not clear how you’d represent that for a trackball. But do you get fine control like a mouse? Does the slightest nudge show up as a step, or is it chunky? Thanks!
