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 on-board 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.
