After a week's delay or more, the Propeller 2 Evaluation Board PCBs finally arrived. We've been out of stock for a few weeks and are starting another build of 200 units today.

  • Nice! In spite of saying I was going to stick with my Rev B board, I may have to get one of these to complete my collection! :smile:

    Good news! I've been waiting for these to be available before I ordered the Rev.C chips... So, can just do one order...

    I see the changes to the 5V headers in some places marked...

    Noticed the /RES pin next to P62 and that jumper header J402 has been removed. I cut the link and installed a jumper there on my rev B Eval. Is there an easy way to disable DTR reset with this board?

    Is there a schematic available for this board yet?

    The alternative RESet is moved to the last accessory header, next to P62. It replaces the old 5V. Presumably there is still a cut-able link somewhere.

    EDIT: It's now on one of the DIP switches. So you easily can change back and forth even. :)

    Those X marks look like rejects.
    Did they send the right pile ? ;)

    Yes and yes. When they send extra PCBs for our evaluation, they mark them with an X instead of provide them for free.

  • Nothing like an IPA challenge :) :) :)

    (And I'm not talking Ale, for our UK friends!!)

    Spot on!

    Dip-switch control of the USB DTR signal
    and
    Diode protected RESn at the programming edge header, labelled with the inverse RES text. So no worries if 5V should get to that pin by accident :)

    Perfect, good job Parallax! Missed the dip-switch change! So BOD was cannibalized?

    Would still like to see the schematic.
  • BOD now an always on feature, with RESn permanently connected to PG flag from 1.8V regulator.

    Sure thing on the schematics- They will be published with the product, if not sooner if time allows.

  • It looks like I have to do my first steps with the latest P2 with the Eval board. For this reason I will make an order in short time. I'm ready to route board to others here in the EU (still including our friends in GB). So anyone interested should PM me.
  • Last Call: To whom it may concern: I'm going to order some components and boards from Parallax and there is a chance to save transport fees and take advantage of July 4th. I'll place the order within a few ours, so please PM any request you want me to order in addition to my own needs... (not P2 related included)
