The Spartan-7 FPGA offers the most size, performance, and cost-conscious design engineered with the latest technologies from Xilinx. Putting this FPGA in the Arty form factor provides users with a wide variety of I/O and expansion options. Use the dual row Arduino® connectors to mount one of the hundreds of hardware compatible shields available, or use the Pmod ports with Digilent’s pre-made Pmod IP blocks for a more streamlined design experience. Arty S7 was designed to be MicroBlaze ready and comes out of the box ready to use with Xilinx’s WebPACK licensing.
