Project Name: OCRP-1



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.

Availability of bare PCBs through Wilhelm Mikroelektronik GmbH

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 (picture).

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.

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.

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.

Availability of assembled boards

Due to low demand we have decided not to offer assembled boards.


Just completly fill in order form 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).
If you need to get in contact with Wilhelm Mikroelektronik, you can send e-mail message to ocrp1@wilhelm.de_NOSPAM.

The following options are available:

There wonīt be any component kits to avoid warranty problems.
