Product Detail

The PAA3905E1-Q by Pixart is an optical motion tracking sensor designed for object motion sensing. It features a wide working distance from 80mm to infinity and requires no focal length calibration. The sensor can auto-detect challenging conditions such as checkerboards, stripes, glossy surfaces, and yawing. It outputs 16-bit motion data and includes a motion detect pin output. The sensor operates with a supply voltage of 1.8~2.1V and an interface voltage of 1.8~3.6V. It communicates via a 4-wire SPI and has a resolution range of 340@35mm to 790@15mm. The package size is 6.0*6.0*2.8mm.
