-This project demonstrated that AD936X chip can combine with low-cost ZYNQ FPGA development boards, especially PYNQ-Z1, and run openwifi without problem. This can potentially become an extremely low-cost openwifi platform.

This can potentially become an extremely low-cost openwifi platform. And with extensions removed, you still have a working(maybe except HDMI) PYNQ capable of any other serious ZYNQ projects.

 *Detailed modification of PYNQ-Z1 coming soon.*
 
+#### Future plan
+
+Current version requires modification of the PYNQ-Z1 board aka 0402 soldering. I'll try if I can get this working with zero modification on PYNQ side. If coming tests show positive result, there'll be a version 2.
