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.

Guides and demos are available to help users get started quickly with the Cmod S7. These can be found through the Support Materials tab.

    Smart, Essential, Cheap

    Posted by Nico Palermo on 27th Feb 2020

    A perfect module if you want to become familiar with the Xilinx Spartan-7 DSP logic and you don't need a board with the peripherals you will never use. The Vivado project examples take minutes to learn. Really nice!

    Easy Modular FPGA

    Posted by John on 4th Dec 2019

    This module is the simplest way to utilize the Spartan S7 without having BGA fabrication available. It is also very cost effective. Making the equivalent circuits, FPGA, triple power supply regulators, JTAG interface, memory fabrication and labor is much higher than the price of the module. The user does not have to concern over signal integrity over making the equivalent circuit. This is a perfect avenue to FPGA development for the engineering student, hobyist or professional wanting to make a working model of their design. There is a generous number of IO brought out to the pins. This module has a small form factor and can be reprogrammed and reused for multiple project designs.
