PYNQ-Z2 is a FPGA development board based on ZYNQ XC7Z020 FPGA, intensively designed to support PYNQ, a new open-sources framework that enables embedded programmers to explore the possibilities of xilinx ZYNQ SoCs without having to design programming logic circuits. Benefiting from programmable logic and advanced ARM processor in ZYNQ, designers can build up more powerful embedded systems with it. Besides, the SoCs can be programmed in Python and the code can be developed and tested directly on the PYNQ-Z2. The programmable logic circuits are imported as hardware libraries and programmed through APIs in basically the same way that the software libraries are imported and programmed. PYNQ-Z2 board integrates Ethernet, HDMI Input/Output, MIC Input, Audio Output, Arduino interface, Raspberry Pi interface, 2 Pmod, user LED, push-button and switch. It is designed to be easily extensible with Pmod, Arduino, and peripherals, as well as general purpose GPIO pins.
What is PYNQ? PYNQ (Python On Zynq) is an open-source project from Xilinx® that makes it easy to design embedded systems with Xilinx Zynq® Systems on Chips (SoCs). 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 users can now create high performance embedded applications with: parallel hardware execution, high frame-rate video processing, hardware accelerated algorithms, real-time signal processing, high bandwidth IO, low latency control. PYNQ utilizes the best advantages of ZYNQ and Python. It has been widely used for machine learning research and prototyping. Use this board with our DF Arduino or Raspberry Pi expansion shield, ultimate possibilities waiting for you!

Jargon buster
Plain-language definitions for the technical terms used above.
- DAC
- A digital-to-analogue converter turns numbers from the microcontroller into a real analogue voltage. It matters if you want to generate simple waveforms, audio-style signals, or variable control voltages rather than just on/off outputs.
- GPIO
- General-purpose input/output pins are microcontroller pins you can set in software to read signals, switch devices on and off, or connect to peripherals. The number of GPIO pins matters because it limits how many buttons, LEDs, sensors, and other parts you can wire directly to the board.
- HDMI
- HDMI is a common digital video and audio connection used by computers, media players, and many displays. If a display kit has HDMI input, it is usually much easier to test with a single-board computer because it can act like a normal monitor.
- I2C
- I2C is a two-wire communication bus used by many sensors and small modules. It matters because several I2C devices can share the same two wires, but each device needs a compatible address and your controller must support I2C.
- I2S
- I2S is a digital audio interface used to send sound data between chips, such as from a microcontroller to an audio amplifier or DAC. It matters if your project needs cleaner digital audio output than a basic buzzer or PWM signal can provide.
- JTAG
- JTAG is a hardware debugging and programming interface used to inspect and control chips at a low level. It matters for advanced development because it can help diagnose firmware problems that are hard to see through normal serial output.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- microSD card
- A microSD card is a small removable memory card used to store files such as audio tracks. For this product, the card is where the sound files live, so its capacity and formatting can affect how many sounds you can use.
- RAM
- RAM is temporary memory used while a device is running, and its contents are lost when power is removed. A “Run in RAM” mode is useful for testing settings without permanently programming the module, but it may not support every feature.
- RGB
- Short for red, green and blue, usually referring to an LED that can mix those three colours. It matters because controlling an RGB LED teaches how separate outputs combine to create different colours.
- Shield
- An add-on board that plugs into a main controller board to give it extra features such as sensing, motor control or communication. Knowing a product supports shields helps you judge whether it can connect neatly into an existing maker-board setup.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
- UART
- UART is a simple serial connection that sends data over separate transmit and receive wires, often labelled TX and RX. It matters because this module is designed to replace a wired UART cable with a wireless link while keeping the same serial data format.
