Hello, I want to buy the ardupilot book, but before I buy it, I want to know if this book contain a knowledge about the development side
Which book exactly is that? Title? Author(s)?
What kind of development information do you want?
Most development information is here:
and in here:
the title: Designing Purpose-Built Drones for Ardupilot Pixhawk 2.1: Build drones with Ardupilot
the author: Ty Audronis
That book is from December 2017, also almost 6 years old. A lot has changed in the last 6 years.
