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 A7 is a small, 48-pin DIP form factor board built around a Xilinx® Artix®-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 A7 also features a clock source, Pmod port, and onboard I/O with LEDs and pushbuttons. There are 44 FPGA I/O signals that are routed to 100-mil-spaced through-hole pins, making the Cmod A7 compatible with solderless breadboards. This form factor makes the Cmod A7 a great option for flexible and affordable prototyping, or learning FPGA and digital logic circuits. At just .7" by 2.75", it can also be loaded in a standard socket and used in embedded systems.

The Artix®-7 FPGA on the Cmod A7 provides the highest performance-per-watt fabric, transceiver line rates, DSP processing, and AMS integration for a cost-optimized FPGA. With the MicroBlaze Soft Processor Core from Xilinx, you can create embedded applications with a variety of peripherals, memory, and interfaces.

If your design does not require the transceiver lines or higher-performance of the Artix®-7 FPGA, we recommend the more affordable Cmod S7, featuring a Spartan®-7 FPGA.

Guides and demos are available to help users get started quickly with the Cmod A7. These can be found through the Support Materials tab.

The Cmod A7 can be programmed with Digilent's Adept software. Digilent Adept is a unique and powerful solution which allows you to communicate with Digilent system boards and a wide assortment of logic devices. Find out more about Adept here.

To create and modify designs for your Cmod A7, you can use Xilinx's Vivado Design Suite. Vivado is a software designed for the synthesis and analysis of HDL designs. Both variants of the Cmod A7 are supported by the free WebPACK edition of the Vivado Design Suite.

If you are using the MicroBlaze Soft Processor Core from Xilinx, you can make use of the Vitis Core Development Kit or Xilinx Software Development Kit to create embedded applications for your Cmod A7.

Note: Xilinx software tools are not available for download in some countries. Prior to purchasing the Cmod A7, please check the supporting software's availability, as it is required for the board's use.

    Great deal for FPGAs. Small form-factor and good price for a strong chip.

    CMOD A7-35T and BusBridge3 Project

    Posted by Steve Purcell on 29th Jun 2023

    I'm very impressed with this board and the BusBridge3 project designed for it. The BusBridge project is a wealth of information and useable code that I've only just begun to delve into and will provide value for years to come working with FTDI chips and Xilinx FPGA's. The board shipped in three days and the projects upgraded to the newest Visual Studio and Vivado and built and ran flawlessly without any modifications. For what I was looking for this product provides value far beyond it's price.

    Small but powerful

    Posted by Mathias on 16th Jan 2022

    This is a very nice little board. I like it very much. Bear in mind that the SRAM only has a 8 bit bus. Also the pmod connector does have 4 differential pairs, but you can only use 3, since one of the pairs is not in the same group.

    Amazing little board!

    Posted by Marcus on 14th Dec 2021

    This has become my favorite FPGA board by far. I have a RiscV32 in it, plenty of RAM and ROM, and any peripheral I need. I use it for projects and to test devices at work. Fits breadboards for easy wiring.

    good price for a powerful tiny FPGA board. Will be nice if the board comes without the PMOD connector.

    Cmod FPGA board works great

    Posted by Marcus Escobosa on 27th Aug 2021

    This is a great little board! I have purchased 2 so far for projects using a riscv32 CPU.

    Much improved USB connectivity

    Posted by David Fergenson on 19th Feb 2020

    I had previously reviewed this product and pointed out that it was not a good module for a beginner but that it was good for an experienced FPGA developer who did not want to have to design an FPGA directly onto a PCB. However, there was a nagging issue with the modules that is no longer true: they now connect flawlessly over USB. They had been picky about cables and took some work to stabilize for programming but they now connect on the first try and are stable.

    Documentation sucks

    Posted by William D. Richard, Ph.D. on 22nd Jan 2020

    The schematic available for the part doesn't have all of the parts documented in the manual shown. Pretty sloppy. I expect better from DIgilent. I am really disappointed. --Response from Digilent-- Hello, The programming circuit in the schematic is considered proprietary. For additional information, you can contact us at [email protected]
