You could try something like this:
you want a 24-pin 0.5mm-pitch FFC cable, plus the extension PCB with 2 connectors on it. You connect the sensor to that PCB, and the long cable to JeVois.
Now this may or may not work. We have tried this with a long cable for the AR0135 sensor and it did not get detected. Maybe there is too much loss in the long cable. Since the JeVois PCB is so small (not much bigger than the above adapter PCB with 2 connectors), you may be better off keeping it close to the sensor and looking at using a long USB cable instead, this is verified to work.
