Success! USB Power Shield v1.0

A special envelope arrived yesterday from BatchPCB – the envelope containing the prototype board for the USB Power Shield v1.0. Or should I say prototype boards – they were kind enough to produce two, even though I only ordered one. Consider me a happy customer, especially because the boards work.

That’s right, the very first prototype board actually functions. I’m amazed too.

Of course, there are some changes I’d like to make – expect to see a v2.0 very soon. A few big things will be happening in the next revision, including addition of power planes and making the board smaller to reduce cost (by 30% ! ).

If anyone’s interested in ordering one of these from BatchPCB, email me and I’ll send you the link and parts list . I don’t want to make it completely public yet with the upcoming revision, which will be cheaper and more stable, but if you want to try it now let me know.

Also expect to see a basic Arduino library for controlling it soon, and we’re working on completing the WootOff application – the pressure’s on now that there is a working board!

    Thanks, second revision is already ordered and waiting for a panel to fill up. I got the last order in about 3 weeks turnaround, which is pretty good. Let me know how yours goes!

    On a side note, I tried charging my MP3 player with it and it worked great, although I need a larger heatsink for the regulator – it was HOT. The WootOff lights (the intended target) work great as well, with much less current and heat.

    For the reference of anyone reading this, it seems the iPhone will not charge without pullup resistors on the data lines. I’m adding space for those on a minor revision 2.1.

    [...] in time to test the USB Power Shield, it’s a Woot-off! I’ll post some pics of the lights in action tomorrow, but for now, [...]
