-Two circuit boards were designed to reduce the amount of wires and the necessity to use external power banks to deliver power to various modules. Both boards use #22 gauge wire which provides sufficient current flow to all the modules. The CAN board schematic shown below groups all the CAN transceivers in a single place so that the +5V power is shared among the CAN transceivers and are all close to the CAN bus. The power delivery board schematic shows how the power is taken from the main battery of the RC car and goes through a DC-DC buck converter to reduce the voltage to +5V from +7.2V. The +5V output of the buck converter delivers power to the CAN board, four SJTwo boards, 5 ultrasonic sensors, and wheel encoder. The output of the ESC in addition to powering the motor also powers the servo. Lastly, the power deliver board has a voltage reading point to monitor the voltage of the battery which is connected to the bridge sensor node.
