Many of you know that we have been struggling with how to make our daughtercard designs available in a useful format that will allow sharing improvements as easily as sharing/diff/patch/merging is done in software. I can only say-- it's not done yet... On the other hand, there's too much 'need to know' info that I've kept bottled up waiting for a great way to make it useful. So we've decided to publish it anyway in the form it's in plus a graphic format (we chose png) just to get going. So, take a look at http://pubs.gumstix.com. Those of you with time let us know what you think about http://pubs.gumstix.com/boards/AUDIOSTIX/PCB00012-R775/ (audiostix II) 1) there's no battery-recharge 2) we will offer it with/without GPS 3) the gps antenna marked is an SMA and it will go on the top (although it's shown on the bottom right now) the contender antennas were hirose u.fl and mmcx. 4) the pinout is straight from the breakout gps (i.e 50mil pitch) And-- of course-- more to come. Thanks in advance, Gordon |

Printing "audio in" and "audio out" somewhere would be even better. - It would be nice to have an optional null resistor or jumper between USB_VBUS and V_BATT, unless there is a good reason to never connect them (?). - Similarly, how about an optional jumper between V_BATT and AD0 ? (The UCB400 has internal resistive voltage dividers on ADx.) -- Pascal |
