Subject: Breakout Boards - msg#00106List: linux.distributions.gumstix.generalprototype with the gumstix boards. I have had several requests for, variously-- a multiple-header board (i.e. several headers tied to the different ports at logic levels) a prototyping area (i.e. 60-pin connector with a breakout area in 0.100" format) a video or LCD recommendation or reference design, a JTAG connector --- and so on. I also had planned on making -- 1) an N-pin DIP daughtercard (N=40 or 60) for the gumstix that would let the gumstix fit into a protoboard, 2) a JTAG connector based on the ezUSB from Cypress, 3) a 3xAAA battery power pack. I want to get going on this ASAP, and I'd love to hear from the mailing list about features you think need to be on a set of break-out boards. Form-factor is also important; i.e. how big a prototyping area?

So I built a breakout board for the connector that gave me standard 2mm spacing pin headers that I connect with ribbon cable. Makes life easier during the concept prototyping. I'll mail you an image separately. Indeed, you don't want to be fighting two problems at the same time. - Kim ------------------------------------------------------- SF.Net email is sponsored by Shop4tech.com-Lowest price on Blank Media 100pk Sonic DVD-R 4x for only $29 -100pk Sonic DVD+R for only $33 Save 50% off Retail on Ink & Toner - Free Shipping and Free Gift. http://www.shop4tech.com/z/Inkjet_Cartridges/9_108_r285 _______________________________________________ gumstix-users mailing list gumstix-users@xxxxxxxxxxxxxxxxxxxxx Next Message by Date: click to view message previewRe: Breakout BoardsIf you make a break out board for the 1st type of stix and then for the second type. It may be useful to make the break out for stix type II have a route part of the pins that correspond to stix type I to it's own pin header. So that someone that is designing for type I can type a type II board and still get the type I board pin outs easily :) i.e. a type I pin header and an "all the rest" pin header, which could also duplicate some of the original pins. In other words a breakout board that is good for guys with both types of stix.
