General purpose I/O wiring USB 3 uEye LE (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	-	3.15/3.3 (see below)	V
Input high range	VIH	2.0	-	3.15/3.3 (see below)	V
Input low range	VIL	0	-	0.15	V
Input leakage current	II	-	-	500	µA
Output high range	VOH	2.2	-	3.15/3.3 (see below)	V
Output low range	VOL	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 USB 3 uEye LE are not potential-free and has no protective circuits.
