can run; if the LED is off, it means that the Robot HAT driver board is not powered
on.
【Tracking】 is the pin interface of Tracking Module.
【WS2812】 is the pin interface of WS2812 Module.
【3.3V-GND】 3.3V power supply interface.
【Uart】 Uart interface.
【GPIO 40-PIN】 General Purpose Input Output (GPIO) is designed as a slot with
two rows of pins on the Robot HAT driver board. GPIO can be used to connect
various peripheral electronic devices and sensors and control or monitor these devices
with input/output level signals. In PiCar Pro products, this GPIO interface is
connected to the GPIO pins on the Raspberry Pi driver board.
【5V-GND】 5V power supply interface.
【IIC】IIC interface. It is also the interface of the OLED screen module.
【MPU6050】The interface of MPU6050 sensor.
【Port】 is divided into Port1, Port2, and Port3 interfaces, which are commonly used to
connect Small LED light.
【Servo port】Servo interface.
【motor】 is divided into motor1, motor2 interfaces.
【Ultrasonic】Ultrasonic interface.
2. Precautions for the use of Robot HAT driver board
When you are performing software installation, structural assembly or program
debugging, you can use a USB cable to power the Raspberry Pi. If the Raspberry Pi is
equipped with Robot HAT, you can connect the USB cable to the USB port on the
Robot HAT. Robot HAT will power the Raspberry Pi by the GPIO interface.
Different Raspberry Pi have different current requirements. For example, the
Raspberry Pi 3B needs at least 2A to boot up, and the Raspberry Pi 4 needs 3A to boot
