Yes, this is a wonderful device, I have been using them here for some months
now.  There are some limitations on the serial port clocking accuracy with
certrain crystal oscillator selections, the good news is that I have one
working at 19,200 using the internal 4 MHz RC oscillator.

They work especially easily with the G4JNT DDS board...
