Revision A1 Features and Specifications This section covers the specifications of the BeagleBone CANBus Cape and provides a high level description of the major components and interfaces that make up the board. Table 2 provides a list of the BeagleBone CANBus Cape’s features. -
Page 14: Key Component Locations
Key Components CAN Bus Interface The BeagleBone CANBus Cape uses an RSZ-3.305HP to provide isolated power sources for the CAN transceiver ISO1050. ISO1050 is a galvanically isolated CAN transceiver that isolates grounds and prevents noise currents from entering local ground. The bus side of the transceiver is connected to a D-Sub 9 connector and provides an option to install a terminal resistor. -
