The CAP Slider 2 Click Board™ is a capacitive touch sensor with XY cross shaped electrodes integrated on a Click Board™. This Click Board™ can sense touch even through plastic, wood, or other dielectric materials, which can be used to protect the surface of the PCB and the sensor pad trace itself. Therefore, this Click Board™ comes with overlay, made of plexiglass. Unlike the mechanical button, the capacitive touch button lasts much longer, it is not prone to damage and wear over time and it is very reliable.
This Click Board™ board feature QS333 sensor which contains a ProxSense® module that uses patented technology to provide detection of proximity and touch conditions on numerous sensing lines.
