Printed Circuit Board
<Picture and information, including links to your PCB>
We designed and implemented two PCBs: CAN Bus PCB and RC Car PCB.

CAN Communication
<Talk about your message IDs or communication strategy, such as periodic transmission, MIA management etc.>
Our message IDs are arranged with priority given to the nodes in the following order: DRIVER, SENSOR, GEO, MOTOR.
We decided to give 32 message IDs to each node and to separate the nodes' message IDs accordingly.
| Node | Message ID Range | |
|---|---|---|
| 1 | DRIVER | 32 - 63 |
| 2 | SENSOR | 63 - 95 |
| 3 | GEO | 96 - 127 |
| 4 | MOTOR | 128 - 159 |

Hardware Design
We used 4 Gravity DFRobot URM09 ultrasonic sensors. These ultrasonic sensors are used by the RC car for the purpose of obstacle avoidance. They use I2C communication to send distance data to the SJ2 microcontroller. The measurement range is 300cm. It takes in 3.3V supply voltage. Using the I2C driver the registers on the ultrasonic sensors were configured and the distance was read from the specified registers in the datasheet.
