Oscilloscope (2 channel, 750ksps) Arbitrary Waveform Generator (2 channel, 1MSPS per channel) 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) The EspoTek Labrador is a USB Device that turns any PC (Windows/Mac/Linux), Raspberry Pi or Android device into a full electronics lab with oscilloscope and more. The software interface was designed from the ground-up to be intuitive for students and makers, while retaining some of the more complex features than experienced engineers can make use of. Best of all, the hardware and software is 100% open source - all code and design files are publicly available on GitHub.
