How do you find this stuff Kevin?? I've been running around in circles the last couple of days trying to get any information on this evaluation board, which is available through Mouser Electronics, though not stocked (they do stock the 4731 board however, as does Avnet...but no documentation.
I sure couldn't find this even as a part on the Silicon Labs website, let alone a data sheet.
The only thing I've come up with is the Si4731-Demo which is actually rather fun, and doesn't cost much more than the Tecsun radio, $64.75 and in stock at Mouser. Details at https://www.silabs.com/Pages/default.aspx and search for Si4731-Demo. You have to register to get the documentation; it's free, though I've now had to re-register twice, as their log-in software doesn't seem to remember things very well.
It's stand alone, but you're limited as to what functions are available. Looks as if it has selectable selectivity. Wonder if this qualifies as an Ultralight, hi
best wishes,
Nick
