<font size=+1><b>Description</b></font>
<p>
OpenCores Reference Platform 1 (OCRP-1) standalone board was designed as a common prototype platform for testing our IP cores. It has a central FPGA for evaluating and testing IP cores, I/O capabilities, DRAM and FLASH memory. It also has several I/O, JTAG and expansion connectors. It even has real-time clock and a battery. Current PCBs have four layers.

<p>
It is a 4 layer multilayer with solder mask, hot air leveling finish and
component print on both sides. All boards have been electronicly tested
against the Gerber data (<a href="ocrp1.jpg">picture</a>).
<p>
Shipping is done by normal air mail in an envelope protected by sealed air.
Each letter will contain an official invoice calling the product "printed
carrier board for education and evaluation purpose". 
Wilhelm Mikroelektronik is not responsible for any problems with customs and they do not give any
warranty on the board. They don't take responsibility for any problems that
might occur when assembling the board and they canīt provide any support for
the board. 
<p>
We would like to stress that the fine pitch SMD parts are not intended for
the unexperienced people. You should be sure that you can assemble it.
If there is actually a problem with any of the boards (this should not
happen because of electronic testing) Wilhelm Mikroelektronik will of course provide a free replacement of the PCB.
<p>
If anybody need the stencils for solder cream. They can provide that, too.
The price per pair (top/bottom) is USD 100 including shipping. Just add to
the order sheet manually.
For manual soldering the stencils are not required.
<p>
<font size=+1><b>Availability of assembled boards</b></font>
<p>
Due to low demand we have decided not to offer assembled boards.
<p>
<font size=+1><b>Ordering</b></font>
<p>
Just completly fill in <a href="http://www.wilhelm.de/opencores/">order form</a> and it fax back to the Wilhelm Mikroelektronik. They will immediatly process the order. There should be sufficient number of boards on stock. Worldwide registered and insured shipping is now per piece. Payment options are credit card or prepayment to their account (if you can't do credit card payment).<br>
If you need to get in contact with Wilhelm Mikroelektronik, you can send e-mail message to <a href="mailto:ocrp1@wilhelm.de_NOSPAM">ocrp1@wilhelm.de_NOSPAM</a>.
<p>
The following options are available:<br><ul>
<li>unassembled board     USD 30,-  (plus USD 10 shipping)
<li>connector set: J1/J2, CONN-F, POD 1-3, B1, KE1    USD 37,- (USD 15 shipping)
</ul>
<p>
There wonīt be any component kits to avoid warranty problems.
