The JeVois-A33 smart machine vision camera combines a camera sensor, embedded quad-core computer, and USB video link in a tiny package.
Included: one JeVois-A33 smart camera + one micro-serial cable to connect to an Arduino or similar.
Note: No USB cable is included with this item. Please make sure you use a mini-USB type B 5-pin cable rated for fast-charging as well as data sync. These cables typically feature 24AWG (or lower) wire gauge for the power lines. If powering from USB 2.0 ports, make sure you use a Y-type cable (which connects JeVois to two USB ports on your computer). If in doubt, we recommend that you purchase USB cables from us, as the ones we sell have been tested and verified to work with JeVois. Please see http://jevois.org/doc/UserConnect.html for more information.
