JTAG pogo-pin connector
in [Design]
|
From: martin_05 on 19 Dec 2009 22:17 Does someone make such a thing off the shelf? I've been using typical headers that match the connector on the programming pod. For example, 2mm to match Xilinx and 0.1in to match SiLabs or Freescale (and most everyone else). The design I am working on now is small in size and the header would simply not fit. I've used custom pogo-pin rigs in the past and so I wondered if anyone makes a production JTAG programmer connector built with them. One could then simply lay down pads or small vias and make the board small (as well as add zero cost to support programmability). We have the capability to custom machine our own, but reinventing the wheel is never a good idea. Any suggestions? Thanks, -Martin

Maybe one of their card edge connectors might work for you. Cheers

Digikey has some spring loaded connectors: http://search.digikey.com/scripts/DkSearch/dksus.dll?Detail&name=ED8165-08-ND I don't know the connectors, but looks like you can solder a header on it and then plug in a typical JTAG ribbon cable connector (or the flying wires of the Xilinx platform cable). The Microchip idea with some additional pins at the adapter and holes in the target PCB sounds good, too. -- Frank Buss, fb(a)frank-buss.de http://www.frank-buss.de, http://www.it4-systems.de
