EAS Electronics

EAS cpldLAB is our digital design protoboard, compatible with Xilinx XC9572/XC95108 CPLD's. Use this lab board to prototype circuits in Verilog or VHDL. You can even design circuits using the schematic entry tools found in Xilinx own easy to use free ISE WebPACK software. The XC9500 series are high performance complex programmable logic devices (CPLD) that can be purchased for under $7 each (XC9572-15PC84C). This is a low cost solution for designing and learning digital logic circuits.

Bare PC Board: $10.00 (Click here for image)

No assembled units or parts kit are available. Bare PC boards are in stock.

Please include $5 shipping and handling for destinations within the continental United States. All other areas, please contact us for shipping charges.

For those only interested in purchasing a single bare pcb board, shipping and handling can be avoided by sending us the cost of the pcb and include a self addressed stamped envelope with your order. Please attach three first class stamps to the envelope with your legible return address. We suggest using cardboard floppy disks envelopes that can be purchased at office supply stores. US only.
