The Cap Touch 2 Click Board™ is a capacitive touch sensing Click Board™ which features the CAP1166, an advanced touch/proximity sensor IC, packed with a range of different touch/proximity functionalities, allowing the development of robust and aesthetically pleasing touch interfaces. Besides six touch-sensitive channels, the sensor IC has six independent LED drivers, with several operating modes, including touch sensor linking, as well as the pulsing and breathing effects.
It also supports Multiple Touch Pattern Detection (MTPD), and a press-and-hold function. Capacitive touch sensor inputs are protected from false detection, which can be caused by low noise and RF interference, providing a very reliable touch-sensing functionality.
