1/12

The Digilent Cmod S7 is a small, 48-pin DIP form factor board built around a Xilinx Spartan 7 FPGA. 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.
