Input logic level
To prevent damage to the GPI pin, connect the GND pin before entering voltage to the DIR_GPI pin.
2, GPO2 output level parameter:
The maximum current allowed through this pin is 25 mA.
When the ambient temperature is 25 degrees Celsius, the relationships between the external voltage, resistance and
output low level are shown in Table 11
