The Red Pitaya teaching materials are really well structured, from the basics to quite sophisticated example applications. The basic introductory chapters cover both digital as well as analog circuit design in a very good way for beginners, with all the necessary information but not so much as to become boring.  

All the chapters contain the required theoretical background and key formulas with good understandable examples. Practical exercises and tasks to do further help in understanding of theory. These exercises are described using text along with key pictures and additionally supported by video live explanations.  

For digital design a Verilog-HDL course and an introduction to FPGA design tools are included, which makes the lecture material complete for easy steps into own practical experiments.  

The Test and Measurement chapter explains typical measurement equipment for modern electronics, like an oscilloscope, logic analyzer or spectrum analyzer, with short video explanations.  

Overall, this is a very well done and complete set of lectures and exercises for learning electronics, starting at the very beginner level and leading students to quite complex own experiments.
