This is about as simple as it gets! A rudimentary 5V supply is included onboard for ease of use. A "current" header is included, to allow the CPLD IDD to be measured - this is another good way to determine if your unknown CPLD is good/bad. The obligatory LED is included (yes, that current is drawn through the shunt connector as well!). A 10 pin JTAG header allows connection to the USB blaster, and the 84pin PLCC test socket is where the D.U.T. goes.
