The TouchKey 3 Click Board™ is equipped with seven advanced capacitive sensors, based on the proprietary QTouch™ technology. Besides quite a large number of QTouch™ capacitive sensor channels, the TouchKey 3 Click Board™ also offers some additional features, such as the Adjacent Key Suppression (AKS™), a technology that ensures correct button press, even when the touch sensing pads are placed close to each other.
