Hi everyone, I’m very new to PYNQ. I tried to run this example notebook [https://github.com/Xilinx/PYNQ/blob/v2.0/boards/Pynq-Z1/base/notebooks/board/board\_btns\_leds.ipynb](https://github.com/Xilinx/PYNQ/blob/v2.0/boards/Pynq-Z1/base/notebooks/board/board_btns_leds.ipynb) on my Ultra96-v2 with PYNQ 2.5. What I found when running this snippet: ```auto from time import sleep from pynq.overlays.base import BaseOverlay ``` is ```auto --------------------------------------------------------------------------- ModuleNotFoundError Traceback (most recent call last) in () 1 from time import sleep ----> 2 from pynq.overlays.base import BaseOverlay ModuleNotFoundError: No module named 'pynq.overlays.base' ``` Why these base overlays don’t exist in the Ultra96-PYNQ build? And how can I control buttons and LEDs on my Ultra96 board from Python? Thank you ---

The notebook and ‘base’ design you linked to is for the PYNQ-Z1. This isn’t compatible with the Ultra96. Try start with notebooks installed on the board. You can find more information on the Ultra96 from the two links here: > **[PYNQ - Python productivity for Zynq](http://www.pynq.io/board.html)** > > PYNQ is an open-source project from Xilinx that makes it easy to design embedded systems with Xilinx Zynq All Programmab Cathal
