What's special about this?
But with decent volume they get pretty cheap - for example there are video converters they have FPGAs in them that you can buy for less than you can buy the FPGA part in single qty - which means the manufacturer of the device is getting the FPGA for 5-10% of list price.
Meanwhile the list price from the manufacturer is $3, but it's completely impossible to order anything as an individual. Not sure why they designed a hobbyist beginner-friendly dev board around a part from a company that makes all their products impossible to buy...
