Board level cameras provide a GPIO interface through an 8-pin 1.25mm Molex connector and a powered I2C interface through a 6-pin 1mm JST connector located on the USB3.0 board. The mating connector for the GPIO interface is a Molex 51021-0800 receptacle with Molex 50079-8100 wire crimp terminals and the mating connector for the powered I2C interface is a JST SHR-06V-S-B receptacle with JST SSH-003T-P0.2 wire crimp terminals.

  • Both have an internal 1.5K ohm pull up resistor to 3.3V
  • Pixelink API-Refer to I2C Bus Communications.
7DATAI2C Data

  • Pixelink API-Refer to I2C Bus Communications.
8n/cNo connection 


Notes 

  • Pin 2 can be used as Trigger or GPI. For Trigger and GPI implementation, review the Trigger and the General Purpose Input Output articles respectively.

  • If Pin 2 is used as GPI, only GPIO with the index 1 can be configured for reading and returning a GPI status value.

  • Pin 4 and Pin 5 cannot be used or modified for additional I2C communication interface.
