 Bring a "Can-Do" Attitude to Your Industrial Drone DesignSponsored by Maxim Integrated Providing predictable and error-free communications, CAN bus networks have been the workhorse of the automobile industry for over thirty years. But they have recently found a new lease on life in other industrial applications, including drones. This design solution shows where and how CAN transceivers can be used in drone designs and explains why it is important that they come with high levels of electrical protection. |
