From Hamsterworks Wiki!
The Digilent Basys3 is the new entry level FPGA development board from Digilent Inc (http://www.digilentinc.com).
It is a significant upgrade from the Digilent Basys2 as it has leapfrogged a generation of FPGAs sports an Artix-7.
It is pretty much the entry level model - it has few connectors, and has no external memory, but it has a lot of useful switches, LEDs and buttons.
Perfect as a low-cost first introduction to digital design.
I've expanded mine with an add-on FX2 breadboard and a few PMODs.
