Re: [Xylo-SDR] Xylo - smt proto boards
Thanks muchly! I know very well of your breadboarding expertise! I wonder if
we 'al la Tony' could produce a kit quickly for breadboarding the Wolfsons
or better the TI series? I am going to try to distribute the Wolfson chips
to those who requested and also the 24 mhz crystals I got from you. The
Wolfson's did not cost me anything and the oscillators were minimal cost, so
I don't want no $ for the package.

Unfortunately the source of proto boards I've used in the past
(http://home.att.net/~jacksonharbor/smt.htm) does not currently have the
board in production.
Nevertheless, here's a Wolfson mounted and ready for me to build up the
remainder of the circuit: http://www.tracey.org/wjt/temp/wolfson.jpg It may
not be pretty but it should be workable, at least for getting the control
Here's how a completed project using this method looks:
http://www.tracey.org/wjt/temp/pcm2900-2-web.jpg -- this is a PCM 2900 USB
Codec I did a while back. Works well enough for prototype purposes. Will
admit the version of the circuit Tony did for the SoftRock was a bit
quieter than this prototype board.
It does look like Far Circuits has two boards that will deal with a 28 pin
SOIC - http://www.farcircuits.net/brdbd.htm#3bds Look at the SMT
Manhattan Style boards, and the 116 pin and 1 28 pin breadboard.
Something to be aware of on these, I do not believe they have a solder
mask, so soldering to them can be a bit more tedious than soldering a board
with solder mask.
