PYNQ is an open-source project from Xilinx® that makes it easy to design embedded systems with Xilinx Zynq® Systems on Chips (SoCs).

PYNQ Z2 board, based on Xilinx Zynq SoC is designed for the Xilinx University Program to support PYNQ (Python Productivity for Zynq) framework and embedded systems development. The board is powered by an Xilinx Zynq-7020 Arm Cortex-A9 + FPGA SoC and it integrates a 40-pin Raspberry Pi compatible header and Analog Devices ADAU1761 24-bit audio codec.

Using the Python language and libraries, designers can exploit the benefits of programmable logic and microprocessors in Zynq to build more capable and exciting embedded systems.

PYNQ Z2 board features include:


  • 650MHz dual-core Cortex-A9 processor
  • DDR3 memory controller with 8 DMA channels and 4 High-Performance AXI3 Slave ports
  • High-bandwidth peripheral controllers: 1G Ethernet, USB 2.0, SDIO
