What is it?

The EspoTek Labrador is an open-source board that turns your PC, Raspberry Pi or Android Smartphone and into a full-featured electronics lab bench, complete with oscilloscope, signal generator and more.

This repo hosts all of the software and hardware that makes Labrador possible.


If you're new to Labrador or oscilloscopes in general, I strongly recommend checking out the fantastic tutorial series produced by Lief Koepsel:
It features well-written, rich articles as well as video content that explains everything more clearly than I ever could!

Getting Started

To download binary (executable) versions of the software, go to:

For the documentation, please visit:

Raspberry Pi Build

Please note that the 32-bit version of Raspbian version 9 (Stretch) or later is required to install this software.

To install Labrador on the Raspberry Pi, open a terminal and paste the following command:
wget -O /tmp/labrador_bootstrap_pi && sudo chmod +x /tmp/labrador_bootstrap_pi && sudo /tmp/labrador_bootstrap_pi

This will automatically download, compile and install the latest version of the Labrador software from source. The whole process will take around 20-30 minutes, so don't forget to pack a snack!
After running it, a desktop entry will appear for the Labrador software (under Education), and running the labrador command from the terminal will launch the software interface.

Additional Extras

There are community contributed 3D printable cases available at Thingiverse, courtesy of SpaceBex and Bostwickenator:

Building from Source

If you're looking to build from source but don't know where to start, Qt Creator is the easiest way to get your toes wet!
When installing, make sure you tick the box to install Qt 5.15 or later.

Once it's installed, open Desktop_Interface/, then Clean All -> Run qmake -> Build All.

If you're on Linux (including Raspberry Pi), then you can also build the software from source by cloning the repo, cd'ing to the Desktop_Interface directory then running:

sudo make install

Then, to launch, just type labrador into the terminal.

To build the AVR software, I use Atmel Studio 7. Just load up the .atsln and push F7. You can use avr-gcc if you don't want to install a full IDE.

The PCB files can be edited in KiCAD 5.0 or later.

Thanks to all.


EspoTek Labrador is a USB device that transforms your PC or smartphone into a fully-featured electronics lab. This repo holds all of the source code!
