Optical Flow Sensor Replacement DIY

Posted by Marius on October 22, 2013 at 9:16pm

Hi, I am new to arduino, world and quad  community. I am in the process of studying...

I came across of: Optical flow sensor module @ ardupilo dot .com

 I see that based on A3080 chip. The diagram connection from above page uses:

-/+

MISO - serial data output

MOSI - serial data input

SCKL - serial clock input

NCS - and chip select

I am wondering if anyone tried to tear up an optical mouse with ADNS-2051  / A2051 and use

it instead. I see on A2051 (16x16 black) the serial i/o is one pin, and there is no chip select, (there is power down, can be used).

    While putting together the ADNS3080 based sensor I looked at a lot of different mouse sensors.  The problem with the one you've selected is it's maximum speed (2300fps) might mean that it's low-light performance isn't very good.  the cpi of 800 isn't too bad although the 3080 is capable of 1600.  You know the 3080 is still available from places like jDrones.
