The following specifications apply to the board level versions of the USB 3 uEye LE. The inputs/outputs mentioned are not accessible in the housing versions.

8-pin plated-through holes (for connector 50 mil/RM 1,27 mm)

Pin	Description	Fig. 445: USB 3 uEye LE PCB version - I/O connector
1	Output supply voltage, 5 V (100 mA)
2	USB ground (GND)
3	Trigger input without optocoupler (+)
4	Flash output without optocoupler (+)
5	General Purpose I/O (GPIO) 1
6	General Purpose I/O (GPIO) 2
7	I2C bus clock signal (internal 2k2 pull-up to VINT*)
8	I2C bus data signal (internal 2k2 pull-up to VINT*)

* This voltage depends on the supply voltage required for the sensor used (see table below)

Attention: The pin 1 is a voltage output of the camera. Do not apply an external voltage on these outputs thus this may be destroy the camera.

You can check the color assignment of the cable on the Website directly at the specific accessory item.

The I/O connector of the USB 3 uEye LE can be equipped with a 2 x 4-pin connecting plug with a 1.27 mm (50 mil) lead spacing. IDS Imaging Development Systems GmbH shall not be liable for any damage to the camera or connected devices arising from installation of the connecting plug.

Note: The maximum length of the I/O cable is 30 m. The cable must be shielded.

Internal supply voltage by sensor type

I2C operation

The I2C bus is operated with a clock frequency of approx. 400 kHz. Multi master mode is not allowed on the I2C bus while the USB 3 uEye LE camera is used.
