 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. And with extensions removed, you still have a PYNQ capable of any other serious ZYNQ projects.
