"A major selling point of this board is the PCIe interface. Most FPGA boards with PCIe will cost over a grand, and will only fit in a large desktop computer."
"Everything needed to program and debug the FPGA is on board, and taking into consideration the low price, it is a great alternative for designing PCIe on a low budget without reducing functionality."
PicoEVB is an affordable, open source, development board which can be used to evaluate and prototype PCI Express designs using a Xilinx Artix 7 FPGA on Windows or Linux hosts. The boards are designed around the Artix 7 (XC7A50T).
While the main intent of PicoEVB is PCIe design prototyping, it can be used as an integrated part of your laptop (or desktop) computer. Use a board as an encryption co-processor for security, or as a hardware-level encoder/decoder for speedy workflows. It’s your FPGA, design what you like.

PicoEVB high-level schematic
Current FPGA development boards are large. Almost all development kits require a desktop PC, or are designed to sit on a lab bench. NanoEVB aims to change this — the entire development kit fits inside a laptop! In addition, the JTAG cable is built-in, no external cables needed- just plug it into a PCIe slot and go.
Furthermore, to explore PCIe designs, currently you need to spend over $1,000. NanoEVB and PicoEVB have PCIe connectivity to the host computer, and as such, you can design PCIe-based solutions and explore Xilinx’s IP for PCIe solutions without spending a grand and without taking up a ton of space.
