EZ1CUSB

EZ1CUSB PRO/CON

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

EZ1KUSB

EZ1KUSB PRO/CON

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

EZ2SUSB

EZ2USB PRO/CON

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

XEM3001

XEM3001 PRO/CON

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)

CONCLUSION

XEM3001 the best Many pins so Parallel EEPROMs are an option Excellent for expandability
