Digilent USB104 A7 Artix®-7 FPGA PC/104 Development Board

Digilent USB104 A7 Artix®-7 FPGA PC/104 Development Board, based on the Xilinx Artix-7 XC7A100T FPGA, brings power and versatility to the PC/104 stackable PC ecosystem. The Artix-7 device provides an extremely high performance-per-watt fabric, making the USB104 A7 Development Board ideal for size, weight, and power-constrained projects. I/O is provided by three 12-pin Pmod ports and a SYZYGY-compatible Zmod port. The Development Board features a USB port with multiple I/O interfaces, from UART to DSPI and DPTI, providing anything from a simple command interface up to a 40MB/s parallel interface, controllable through the Digilent Adept API. The USB104 Development Board measures 95.89mm x 90.17mm and provides the standard mounting holes with standoffs included.
