GPIO Pins The Raspberry Pi GPIO Pins The Raspberry Pi™ hardware shares digital pins between the GPIO, Serial, SPI, and I2C interfaces. Enabling or disabling the SPI and I2C interfaces changes the availability of specific pins for use as GPIO pins. ...
In this tutorial, we are going to take a look at the basics of the Raspberry Pi’s GPIO pins, also known as the general-purpose input and output pins. These pins are essential for communicating with other circuitry, such as extension boards, custom circuits, and much more. LATEST VIDEOS ...

GPIO代表“通用輸入/輸出”,正是這些引腳讓Raspberry Pi發揮了其功效。因為這些引腳沒有特定的功能,所以可以設置為某個專用功能,例如控制信號。 設置為輸出的GPIO引腳可以提供3.3V(高電平信號)或0V(低電平信號)的電壓。當設置為輸入時,該引腳可以讀取相同數值的電壓。
