General Purpose I/O wiring uEye LE USB 3.1 Gen 1 (PCB version)

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:

	Symbol	Min.	Typ.	Max.	Unit
IO voltage range	VCCIO	0.0		3.3	V
Input high range	VIH	2.0		3.3	V
Input low range	VIL	0.0		0.15	V
Input leakage current	II			500	µA
Output high range	VOH	2,2		3.3	V
Output low range	VOL	0,0		0.4	V
Output current high	IOH			0.2	mA
Output current low	IOL	-1.0			mA

The general purpose I/Os of the uEye LE USB 3.1 Gen 1 are not potential-free and has no protective circuits.
