2. EZ1CUSB

3. EZ1CUSB P RO /C ON Pro’s Don’t have to reprogram at boot Built in USB  FPGA interface Has the most I/O Pins Con’s Most expensive Never programmed an Altera before Soldering would be difficult

4. EZ1KUSB

5. EZ1KUSB P RO /C ON Pro’s One of the cheapest Already built in USB  FPGA interface Con’s Least amount of I/O Pins Never programmed an Altera before Must be reprogrammed at every boot Hard to solder

6. EZ2SUSB

7. EZ2USB P RO /C ON Pro’s One of the cheapest Already built in USB  FPGA interface Familiar with Xilinx products Con’s Least amount of I/O Pins Must be reprogrammed at every boot Hard to solder

8. XEM3001

9. XEM3001 P RO /C ON Pro’s One of the cheapest Don’t have to be reprogrammed at start Built in USB  FPGA interface High level of support and tools (SDK’s and API’s) Good number of I/O Pins Familiar with Xilinx Spartan 3 FPGA’s Con’s Hard to solder (easier than the other three)

10. C ONCLUSION XEM3001 the best Many pins so Parallel EEPROMs are an option Excellent for expandability
