Tech note from Maxim Integrated on using the proven robustness of CAN Bus to drone’s internal parts communication. Link here (PDF)
Providing predictable and error-free communications, CAN bus networks have been the workhorse of the automobile industry for over thirty years. However, they have recently found a new lease on life in other industrial applications, including drones. In this design solution, we show where and how CAN transceivers can be used in drone designs and explain why it is important that they come with the high levels of electrical protection when used in this application.
