Cmod S7 Breadboardable Spartan-7 FPGA Module

The Cmod, or Carrier Module, family of products is designed to offer quick, simple, and flexible integration of an FPGA into circuit design, prototyping, and learning/hobby projects.

The Digilent Cmod S7 is a small, 48-pin DIP form factor board, populated with 36 pins, built around a Xilinx^® Spartan^®-7 FPGA that brings FPGA power and prototyping to a solderless breadboard.

The board includes a Quad-SPI flash for programming, as well as a USB-JTAG programming circuit and USB-UART bridge. The Cmod S7 also features a clock source, Pmod port, and onboard I/O with LEDs and pushbuttons. There are 32 FPGA I/O signals, 2 FPGA analog input signals, an external power input rail, and ground that are routed to 100-mil-spaced through-hole pins, making the Cmod S7 compatible with solderless breadboards. This form factor makes the Cmod S7 a great option for flexible and affordable prototyping, or learning FPGA and digital logic circuits. At just .7" by 3.05", it can also be loaded in a standard socket and used in embedded systems.

The Spartan-7 FPGA on the Cmod S7 fits performance into a small form-factor packaging. With the MicroBlaze Soft Processor Core from Xilinx, you can create embedded applications with a variety of peripherals, memory, and interfaces.

If your design requires transceiver lines or more FPGA resources, we recommend the higher-performance Cmod A7, featuring an Artix-7 FPGA.
