The Parallella is feeling blue..

Posted by Adapteva (Creator)

The fabs are back and as you can see we have made a late change to the look of the Parallella board. It's now blue! Interestingly enough I don't think the question of color ever came up once during the last year. Hopefully most of you won't mind the change. Designer's choice:-)

The changes made to this RevC board (or Gen 1.1) include;

  • Fixed HDMI wiring issue
  • Made the USB port host-mode only as default build option
  • Removed flaky mechanical jumper for 5V mounting hole power feed
  • Added more ground vias for improved thermal performance
  • Changed Tantalum caps to ceramic caps to avoid material procurement issues

The new board sources can be found HERE.

Here are the 200 fabs about to be sent off to the local contract manufacturer this morning for final assembly. Expecting the first boards to come off the line in 5-7 business days if there are no issues. Fingers crossed...

      The good news is that the new boards are on schedule and will arrive tomorrow.

      The big "announcement" has been delayed by a few more days, unfortunately the timing is largely out of our control.

      @beau, @andres The caps being switched out were 100uF decoupling capacitors for the Zynq supplies. We "should" be OK baesd on calculations and reference design comparisons.

      @all Thanks for the encouragement and feedback about the color. Looks like we made the right choice!

      Thanks for the updates!
      Anybody else going to work on haskell (ghc) support for these systems?

      Nice! Glad to hear things are moving a little better. Thank you for your diligence.

      The strips on the top and bottom break off, I think.

      Glad there's progress!

      Seems like they aren't meeting the small size as initially desired :)

      Love the blue ...
      But also worried re the Tant => Cer capacitor change.
      Tantalums damp resonances and so are good for decouplers.
      Ceramic are higher Q. I like to use both, for best performance.

      it's magnificent; scout's honor!

      I am so looking forward to see what can be done with that piece...

      With the new ceramic capacitor - did you recheck that the different (lower) esr of ceramic is still OK?

      Here some hints what I mean:

      Looks awesome!

      Parallella plans became reality. Can't wait to play with it :)

      Cheers,

      greeeeaaaaaaaat!
      I can't wait to get mine!

      Nice one, well done :)

      I love blue boards, and Yay on the progress!

      @Anton We were having some issues booting from a USB drive and wanted to take the safe root. One of the issues was not having the required 100uF capacitor on the VBUS. All the Zynq boards we have reviewed so far all had build or jumper options for choosing between OTG and host mode.

      Blue is good! Thanks:-)

      @kenichi Mine too!

      Can you give some more details about the change "Made the USB port host-mode only as default build option"?

      The blue reminds me of those old iMac boards
