PYNQSDR v1.2

This version, fabricated with SMT, works without any problem. In the next version more minor things will be optimized for production.

PYNQSDR v1.1

This version has a simplified circuit design, and it works. v1.0 has some problem so won't be released.
Attached is the manufacturing file, use at your own risk.

PYNQSDR v0.9

PYNQSDR v0.9. This combination(pynqsdr, br2, br4) works without known problem on unmodified PYNQ-Z1 board. Yet it's not recommended to use these board files for your own fabrication at this stage. If you really want, be sure to contact me first.
