Re: [Xylo-SDR] Xylo - smt proto boards



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.
Cheers,

little easier to handle these itty bitty peppercorns! I know that Bill -
KD5TFD has done a lot of this and has some small prototype board sources.
