Cmod S7 Breadboardable Spartan-7® FPGA Module
Cmod S7 Breadboardable Spartan-7® FPGA Module
Size, performance, and cost-optimized FPGA module on Digilent's Spartan 7 XCS25
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”, 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.
