2, GPIO status LED and power 5V / 3.3V indication. GPIO output or input level high LED on, output or input level low LED off. 5V blue, 3.3V red, GPIOs green. The position of the LED is in a one-to-one correspondence with the position of the Raspberry Pi 2x20pin connector, and the logic level of the GPIO can be observed very quickly and intuitively.
