GPIO specifications
The two GPIOs (general purpose I/O) can be used as inputs or outputs. This selection is made by software using the corresponding SDK API functions. Please observe the following criteria:
•Input: 3.3 V, max. 5.0 V input voltage
•Output: 3.3 V, max. 4.0 mA (UI-122xLE/UI-124xLE/UI-125xLE/UI-125xLE/UI146xLE/UI-154xLE)
•Output 3.1 V, max. 4.0 mA (UI-164xLE)
•Output 3.0 V, max. 4.0 mA (UI-148xLE/UI-149xLE/UI-155xLE/UI-158xLE)
