Please note: The Arty A7-35T variant is no longer in production and is now retired.

The Arty family of Digilent FPGA/SoC boards was designed with versatility and flexibility in mind. With universally popular Arduino™ headers and multiple Pmod™ ports, an Arty will be the most adaptable FPGA/SoC board in your toolbox.

The Arty A7 is a ready-to-use development platform designed around the Xilinx Artix-7 FPGA family. With the Artix-7 devices, the Arty A7 board provides the highest performance-per-watt fabric, transceiver line rates, DSP processing, and AMS integration in the Arty family. With the MicroBlaze Soft Processor Core from Xilinx, you can create embedded applications with a variety of peripherals, memory, and interfaces.

The Arty A7 is supported by Xilinx's Vivado Design Suite, including the free WebPACK version. You can also leverage the Vitis Core Development Kit or Xilinx Software Development Kit to start developing for the MicroBlaze processor with no prior FPGA experience.

There are two variants of the Arty A7: The Arty A7-35T features the XC7A35TICSG324-1L, and the Arty A7-100T features the larger XC7A100TCSG324-1.

If the Arty A7 offers more performance than your application requires, the more affordable Arty S7, featuring the Spartan-7 FPGA, may be a better option. If you are looking for an SoC-based development board, consider the Arty Z7, featuring the Zynq-7000 APSoC.

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

Note for repeat customers: There has been a change to this product. Please see the memory section of the Features tab.

The Arty 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 Arty 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 Arty 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 Arty A7.

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

    okay but limited

    Posted by eda-user on 9th Mar 2024

    I've had great success with this little board. The documentation is great and one can make some pretty capable designs on it. I wish the vendor offered a 200-T variant, and I ESPECIALLY wish they didn't jam all that built in RAM on it, which is nearly impossible to use. Would rather have the extra pins to wire external memory for physical Harvard architecture. Then I'd rate this part a 5-star.

    having incredible amounts of fun

    Posted by Jaymin on 16th Nov 2021

    My first ever FPGA! I've had this board for two years and I've made one retro console, two different GPUs, and and a blinking light demo. The board has insane resources, and I have yet to come close to hitting its limits. Definitely get the 100t, as the extra BRAM comes in handy for caches

    Arty Board A35

    Posted by Derick Voegeli on 3rd Mar 2021

    Bought this to replace a board I lost. Loved it, so I bought it again. Haven't been able to use the new one because it wont connect. Tech support hasn't been to supportive yet, but waiting for response and a way to use the board.

    Great so far

    Posted by Travis Grice on 29th Aug 2020

    I haven't had much chance to play with it, but it passed the blinky test (with help from the programming guide). I like the right-angled Pmod connectors, the Quad-SPI Flash, and the different options for user interaction (4 buttons, sliding switches, and rgb led's). The usb/jtag connection is very secure to the board and unlike some of the boards I've worked on in the past the layout of the ports allows the board to be placed on a table and be very stable. The rubber feet are a nice touch.

    false advertisement

    Posted by Saulius on 12th Jun 2020

    It is advertised on Xilinx website that "Artix-7 35T Arty FPGA Evaluation Kit" cost $99 but here its is 30 dollars more expensive. $129 to be precise. Can someone explain where does this difference comes from?

    Good but documentation could be improved

    Posted by Digilent Customer on 1st Nov 2019

    I'm used to the world of microcontrollers and wanted to discover FPGAs. Nice board, but a bit disappointed by the documentation. A few "tutorials" are provided but without much explanations. Able to upload them to the board and do their job, but would have appreciated like a progressive course on FPGAs. Maybe starting from very basic examples, and then building up to more advanced stuff. I wasn't blocked at any point, everything is working fine, but the learning curve is steep coming from the microcontrollers world.

    Not worth the cost and poor tools

    Posted by Howard Honig on 19th Aug 2019

    I purchased this board to follow the "Integrating Arm Cortex soft CPU in FPGA's" and was terribly disappointed, despite the fact the online class was well thought out and delivered expertly. After completing the class I realized it is not even worth taking the board out of the box it was delivered in. What a waste of $150. I found the Xilinx tools much too difficult forcing too many steps or clicks with the nonintuitive knowledge to use them. I've used Altera before and found it so much easier. Even though I'm a noob when it comes to Xilinx I can't imagine any situation which Altera products wouldn't be just as good with a short time to market.

    Great for working out ideas and designs

    Posted by Digilent Customer on 10th Jan 2019

    Picked up the Arty A7-100T in preparation for a project that would be needing a capable mid-range FPGA, Ethernet connectivity and a bit of RAM. Having the Pmod connectors and Arduino shield style connector makes for rapid prototyping.
