 To prevent damage to GPIO pin, please connect GND first and then input voltage in Line 2 pin.
Line 2 Configured as Output
The maximum current is 25 mA and the output impedance is 40 Ω.
The relation among external voltage, resistance and the output level low is shown below.
When the voltage of external resistance (1 KΩ) is pulled up to 5 VDC, the logic level and electrical
feature of configuring Line 2 as output are shown below.
