PAA3905E1-Q

PAA3905E1-Q is an optical motion tracking chip designed for motion tracking and to stabilize hovering drones. The working concept is based on optical navigation technology to measure the changes in direction and magnitude of movement (delta x and delta y). It has a wide working range from 80mm to infinity and is ideal for far-field tracking applications. One of the key benefits of this chip, is the ability to function in a very low light condition, i.e. 5 lux. The chip can automatically switch to 3 different modes, depending on the brightness of the environment.

Utilizing its Digital Signal Processing System (DSPS), the PAA3905E1-Q chip does not require any telecommunication signals to process the XY positioning. Hence, it is capable of providing XY positioning in any environment, including GPS-denied areas.
