I guess I am not the right target audience for this book. The author spends an awful lot of time explaining how to use the Linux system running on Beagle Bone. To be fair it is exactly what you want when you are a Windows user, get a Beagle Bone and have to deal with an embedded Linux system for the first time. But for everyone who is already familliar with Linux and just needs BB-specific information half of the book is old stuff. You get an introduction on how to access the GPIO pins from the Linux command line and from Python and that's where it ends. Contrary to most Arduino Books this does not cover electronics at all. In this regard this book alone will not enable you to build your own BB-controlled projects.
A bit disappointing for me but good for absolute novices. I bought the kindle version so I can live with what I got for my money.
[+] Covers Beagle Bond and Beagle Bone Black [+] well written [-] too much Linux [-] not much about electronics. Beginners will need another book
