Angle click carries an A1332 contactless magnetic angle position sensor. The sensing circuitry relies on the Hall Effect to detect the vector of a nearby magnetic field in a 360º two-dimensional plane parallel to the surface of the chip.
Note: This sensor is not recommended for new design. This product is obsolete.
Camera click carries OV7670-VL2A, a low voltage CMOS image sensor, connected to an onboard FT900 MCU through a parallel camera interface.
