7,000 P2 Rev. C Chips delivered to Parallax!

We're taking care of the advance orders for 90-unit trays first, then we'll allocate these among the following uses:
- additional trays of 90 units for customers who have not ordered
- P2 Evaluation Boards Revision C
- uses on a P2 Module (which is not designed)
- for sale individually
At this stage our priorities are for Chip to finish the debugging design, for Jeff to get the Propeller Tool working, applications, and consider a production order. The 7,000 chips we've received will need to last us until we place a production order, which has a 12-16 week lead time and a tremendous expense. We've got some business strategizing to do along with engineering work.
We'll see. We need to place a production order to bridge the supply gap, in which case running out would feel okay. The production order has not been placed and we're just looking into it right now. I'm mostly concerned about tools, objects, and getting up to speed myself.

I would also like to put in a *strong* vote for Parallax to "officially" supporting ERSmith's amazing FastSpin/BASIC/C/assembly suite. That compiler is like a Swiss army knife. It has something for everyone and it does it all well.
I'm excited and chomping at the bit to get my hands on some production silicon. (I have an evil plan to take over the world using Parallax and Total Spectrum Software products!)
Another milestone crossed.
Ordering form US directly is a pain, because of time and
i wish there where a German distributor.
Surac, we haven't brought the mainstream distributors on board yet since we're in the early adopter phase. It would create demands we are still unable to support.
I've got three solutions for you. Contact Oliver at ELMicro in Leipzig. We can sell him whatever you want to buy. Or go online to parallax.com and select USPS, which is quite inexpensive.
If you don't like any of these options, I'll just drop a board in the mail to you. So, you choose and let's get your problem solved.
DiverBob, we've made some changes to the P2 Eval Board and the new PCBs arrive in about a week. The changes were extensive and require a new pick-and-place file, so it'll likely be the end of June before we have the new P2 Eval Board Rev C ready.
The P2 chips may be ready to sell this week. We just have to figure out a few things about packaging and minimum order quantities (probably a 4-pack).
Thank you very much for the offer!
I have already ordered all I need directly from Parallax US
I just wanted to point out that shipping and customs can be
I'm contemplating designing a shield-like board that plugs into all the headers from above...
Except the top-left header 5v pin was changed to Reset.
And the bottom-right header 5v pin is now Not Connected.
And bottom-right is P32..P39?
bottom-right being the 5v pin next to P30
I'll get an image posted tomorrow.
RevB and RevC remain 100% code compatible.
The differences from B to C:
BOD is removed from the dipswitch and instead Propeller RESn is permanently connected to the 1.8V regulator PG signal.
USB RES is on the dipswitch, which enables the user to disconnect the USB reset (DTR) signal from the Propeller RESn pin.
The 5V pin which was next to P30 has been removed, and that pin is now unconnected. A white silk square is provided if a user wanted to connect that pin to something and label it.
The 5V pin which was next to P62 has been replaced with a RESET input to the Propeller RESn. The WiFi module could connect here, for example.
The unpopulated DTR/RESn pads which RevB had (near the SD socket) have been removed as the above improvements replace the need for those pads.
Some improvements to the USB power circuit to improve protection from edge-case faults.
Thanks! It's good news that the Rev B and Rev C boards are code compatible.
@VonSzarvas You mean "NOW unconnected", right?
