GPIO Function Description

  • GPIO: Configurable as input or output for receiving or sending digital signals.

  • 3.3V/5V: Provides power voltage; 3.3V is typically used for logic levels, while 5V is used for peripherals requiring higher voltage.

  • GND: Ground, used to complete the circuit.

  • PWM: Generates Pulse Width Modulation signals, typically used for controlling motor speed, brightness, etc.

  • UART: Used for serial communication to send and receive data.

  • I2C: Used for communication with I2C-compatible devices (e.g., sensors, EEPROM).

  • SPI: Used for high-speed data transfer, communicating with SPI-compatible devices (e.g., displays, sensors).
