The „36“ is the hex address 0x36 and indicates that no driver is loaded yet. If a driver would have been loaded
it would show as „UU“ in location „36“.
Connecting the cable for the cameras or B101 modules
The cameras are connected with the standard 15 pin FFC cable with 1.0mm pitch. To plug in the cable just lift
the brown hatch of the connector, insert the cable the press the hatch down.
Note: please make sure that the contacts of the FFC cable face down. They have to be on the opposite
side of the brown hatch.
The cable is now safely locked in place. Some cables may have lengthy stiffeners on the opposite side of the
contacts. So it may be difficult to slide the cable in, as the connectors are placed close to each other. In this
case please use scissors to shorten the FFC cable. So contact length of 2mm is fine for the connectors on the
J20 module.
Auvidea supplies FFC cables with contact on the same side in various lengths.
Note: The Pi cameras and the B101 require FFC cables with contacts on the same side.
