Digilent USB 104 A7 - Artix-7 FPGA Development Board in PC/104 Form Factor

The first Digilent board to adhere to an industry-standard form factor, the USB104 A7 brings power and versatility to your PC/104 stackable PC. The board measures 95.89 mm x 90.17 mm and provides the standard mounting holes with standoffs included. The USB104 A7 features the industrial temperature-rated Xilinx Artix-7 XC7A100T. Artix®-7 devices provide the highest performance-per-watt fabric making the USB104 A7 ideal for size, weight, and power (SWaP) constrained projects.

I/O is provided with onboard LEDs and push-buttons, and, of course, three 12-pin Pmod ports. A SYZYGY-compatible Zmod port is available as well, allowing for high-speed signal acquisition and generation. An onboard USB hub and controller conveniently interfaces the USB104 A7 with JTAG, UART, and a parallel data interface (DPTI) through a single connection. The DPTI data transfer interface provides host-to-FPGA data transfer and is easily managed with Digilent’s Adept 2 application. This ease of use and high-speed data transfer is especially useful for deployed systems.

The USB104 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 (supported on the Artix-7) with no prior FPGA experience.
