mini Board Lab and Companion

Description

With the rising of high quality opensource tools for FPGAs new opportunities are emerging to discover and build better digital architectures. This board is intended to explore & research the world of modern digital systems that requires large memory bus and high-speed peripherials.

Specs:

• Large xc7k420t FPGA design space
• Two DDR3 SO-DIMM sockets having 128 (2 x 64) bits wide access
• USB3 5Gbps/s data access over x32 wide independent FIFO
• USB2 outband (same usb port) permanent JTAG and UART independent access
• Two M.2 (M-key), 4 x SERDes lanes each, PCIe & SATA mappable
• Four QSFP sockets 4 x SERDes lanes each, with up to 10Gb/s line rates

Can be used in any USB port right from the tips of fingers, no cables, no wires but full control.
