The CAN Node is a product of a collaborative effort with Ardupilot, stemming from a shared ambition to establish CAN peripherals as a standard in the drone community. Unlike other boards with open-source hardware but closed-source code, the CAN Node is fully open. The CAN Node F303 represents the second iteration of our CAN Node, offering increased flash space.
