Electronics From REXQualis on Amazon

The item has been soldered and assembled. Support for Raspberry Pi A+ 3A+ B+ 2B 3B 3B+ 4B

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. The driving current of each LED is only 0.1mA, so you don't have to worry about it affecting the read and write status of GPIO.
