Controller area network bus star-shaped network connector and FPGA

The utility model discloses a controller area network (CAN) bus star-shaped network connector and an FPGA. The CAN bus star-shaped network connector comprises the following components: a CAN transceiver for receiving and transmitting signal; the FPGA which is connected with the CAN transceiver for performing logic arbitration to the signal received by the CAN transceiver. Through the CAN bus star-shaped network connector of the utility model, each node can operate independently. Furthermore the failure of one node wherein does not affect the operation of the system.
