Re: [Xylo-SDR] Xylo - smt proto boards
I've been buying from them for years but their header boards are a little
pricey, but they do have a lot of CPU boards at reasonable prices. Also
they don't have TSop packaging which what we need for the A/D
projects.
I have used their CPU development boards quite often, about a month ago I
bought two AVR boards from them, and will buy more in the future. They
get their board from Olimex, which also do custom PCB's at a very
reasonable price without a lot of restrictions that others place on
you
Thanks

I fail to see why doing the same thing over and over and getting the
same results every time is insanity: I've almost proved it isn't; only a
few more tests now and I'm sure results will differ this time ...
