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 
sigs correct.

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.
