No. Pretty cheap, it's a very tiny board....


I got a discount for 5, and he has a couple left...

It is open hardware also, with a schematic supplied, open source
driver (not a kernel driver yet), I was very happy to support this

I have looked for usb equivalents, btw, and haven't found anything
inexpensive. And in the case of cero I'd wanted something that could
on the internal serial header...

I note that theoretically the BBB also has an on-cpu hwrng but
documentation on it from TI is lacking. Perhaps someone could lean on
TI to free that information up in the post-snowden era?

(my take on it is the more hwrngs the better, one from china, one from
russia, one from the USA...)

/me goes back to converting his dns/mail/vpn server over to a BBB....
