About Labrador:

Labrador is EspoTek’s first commercial product: a tiny yet powerful device that transforms your PC or smartphone into a fully featured electronics lab, complete with an oscilloscope, signal generator, logic analyzer, multimeter and power supply!
Everything is controlled using a multi-platform software interface that was designed from the ground up to be both feature rich and easy to use.
Both hardware and software are 100% open-source.  It can plug directly into a standard breadboard, and is only 35x35mm in size.

But best of all, it’s available for only $29, including free worldwide shipping!
Hit the button below to order now!  (Micro USB Cable not included.)

Or, alternatively, you can purchase through one of our distributors.

Specs at a Glance:

  • Oscilloscope (2 channel, 750ksps)
  • Arbitrary Waveform Generator (2 channel, 1MSPS)
  • Power Supply (4.5 to 15V, 0.75W max output, with closed-loop feedback)
  • Logic Analyzer (2 channel, 3MSPS per channel, with serial decoding)
  • Multimeter (V/I/R/C)
  • Software compatible with Windows, OSX, Linux and Android.

Software:

Above is an example of what the software interface looks like!
Here, the signal generators are generating two different waveforms (sine and sawtooth), while the oscilloscope displays the two waveforms and the horizontal and vertical cursors measure the sin wave.
Of course, if you’re a beginner, you don’t need to be doing all of that at the same time!

The Desktop software interface can be downloaded from here.
The Android software can be downloaded from Google Play.

¹ – 12-bit sampling is available at 375ksps, single-channel only.
² – This figure is an approximate “maximum detectable frequency” dictated by the sample rate.
³ – This figure is for source current. Current is sunk partially into the opamp driving the signal gen and partially into a 1k resistor. Thus, maximum sink current can be calculated by dividing the output voltage by 1k and adding 50µA. This configuration was chosen so that capacitive loads could be driven without significant nonlinearities. In simpler terms, this means that if you’re trying to drive current into the waveform generator through use of an external current source, then the maximum current that the waveform generator can handle is reduced. (This is not something that would be an issue for most people.)
⁴ – The Power Supply is controlled by a closed-loop feedback loop that ensures the DC voltage across output remains constant. Thus, it has nonlinear elements, but can still be approximated by a Thévenin circuit with Vth = Vo and Rth = 0.
⁵ – Multimeter ranges vary with reference resistor used.
