The USB104 A7 conforms to the industry-standard PC/104 form factor, and brings power and versatility to your PC/104 stackable PC. It features an Xilinx Artix-7 XC7A100T. Artix®-7 devices provide the highest performance-per-watt fabric making the USB104 A7 ideal for size, weight, and power constrained projects. I/O is provided with three 12-pin Pmod ports, a SYZYGY-compatible Zmod port. It 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 AdeptAPI.
