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. All Labrador users have access to the best support possible: a direct line to the product developer. If you have any issues or suggestions, simply send a question to the EspoTek Amazon Storefront and I'll do what I can to help.
