PicoEVB

The PicoEVB fits in an M.2 2230 key A or E, which is common in newer laptops. Can also fit into a full-length mPCIe slot with an adapter.

Details

The Xilinx Artix dev kits that fit in your laptop. A convenient, affordable way to explore Xilinx PCIe IP.

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).

Use Cases

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.

Open Source Software & Hardware

The board schematics in their final form (PDFs) will be published under a permissive license. In additon, major software components are open source:

  • The “cable driver”, is already CC0 licenced.
  • All of the host code (PCIe drivers) used in the prototype comes from Xilinx under GPL.
  • The FPGA project is derived from a freely available Xilinx sample project.

Files are being published in the project GitHub repository.

Compact Size

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.

Affordable

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.
