The Digilent Cmod S7 is a small, 48-pin DIP form factor board populated
with 36 pins and built around a Xilinx Spartan-7 FPGA. The 32 FPGA digital
I/O signals, 2 FPGA analog input signals, an external power input rail, and
ground are routed to 100-mil-spaced through-hole pins, making the Cmod S7
well-suited for use with solderless breadboards. At just 0.7” by 3.05”
inches, it can be loaded in a standard socket and used in embedded systems.
The board also includes a programming ROM, clock source, USB programming
and data transfer circuit, power supplies, LEDs, and buttons.
