Something I noticed about the CFA 635

Okay, this is probably really stupid, but what is the other connector on the back of the display for aside from the connector for the USB and the one for the SCAB?? :confused: :confused: :confused: :confused:
And yeah, I'm new here, but have been getting stuff from here for a little while now.

That connector has a ground, 5v, and 8 pins that are copies of the pins that go to the LEDs, plus 8 additional pins that are connected to the processor, but otherwise unused.

It is documented in the data sheet.
