The Castor is a right-handed ergonomic chassis with a moulded, grooved shape to accommodate all 5 fingers. The shell features a 4-layer rubber coating to provide a soft-touch feel along with optimum grip. Behind the scenes we have a 32bit, 32MHz ARM processor to provide the processing power required by that PMW-3310 optical sensor; the PixArt sensor is capable of 10,000 DPI (5,000 DPI native).
