5. ELECTRICAL CHARACTERISTICS
5.1 Absolute Maximum Ratings
Absolute maximum ratings for supply voltage and voltages on digital and analogue pins of the module are listed below.
Exceeding these values causes permanent damage.
The average PIO pin output current is defined as the average current value flowing through any one of the corresponding
pins for a 100mS period. The total average PIO pin output current is defined as the average current value flowing through
all of the corresponding pins for a 100mS period. The maximum output current is defined as the value of the peak current
flowing through any one of the corresponding pins.
