1.3、Analysis of Frequently Asked Questions about Expansion Boards

A: How to control the expansion board of Jetson Nano? How to communicate with expansion board?

Answer: Jetson Nano sends serial port data and transmits it to the expansion board through the USB port. The expansion board integrates a microcontroller to receive and parse the serial port data and then process the specific commands to be executed.

B: How to power the robot? Does Jetson Nano need another power supply?

Answer: The car is equipped with a battery pack at the factory. Insert the battery pack into the DC 12V power T-port of the expansion board, turn on the main power switch, and the expansion board integrates a voltage conversion chip to provide DC 5V power, which is transmitted to the Jetson Nano through the DC 5V power line. powered by.

C: Which functions on the expansion board are managed by the microcontroller? ?

Answer: The parts managed by the microcontroller on the expansion board include: robotic arm, active buzzer, attitude sensor, PWM steering gear, motor, RGB colorful light bar, button KEY1, RESET button, SBUS interface, CAN interface, etc. .

D: How to update the microcontroller firmware of the expansion board? Why update microcontroller firmware?

Answer: The microcontroller integrated with the expansion board has already been programmed with firmware before leaving the factory. Please do not update the firmware unless necessary. If you need to update the firmware, please refer to the tutorial on updating firmware to update the firmware of the microcontroller.

E: What is the difference between expansion board hardware versions V1.0 and V3.0?

Answer: Hardware version V3.0 mainly upgrades the IMU chip to ICM20948, adds a SWD debugging interface and an external switch interface, supports the Raspberry Pi 5 power supply protocol, and can provide 5.1V/5A power supply for the Raspberry Pi 5. It has been modified and optimized. Part of the circuit, etc. Version V3.0 requires the use of Python library V3.3.X or above.
