In terms of the working principle of the SX9500EVKA, it is based on a capacitive sensing technology. This device makes use of two sensing electrodes, one driven and one static. When a positive voltage is applied to the driven electrode, an electric field will be generated between the two electrodes. If an electrically conductive object (such as a finger) comes in contact with the static electrode, the electric field will be disrupted, resulting in a change in the current through the capacitive sensing circuit. This change in current is detected by a device driver, which interprets it as an input. Using this technology, the SX9500EVKA is able to accurately detect and recognize various capacitive inputs.

The SX9500EVKA is an ideal tool for developers and engineers looking to quickly and efficiently test and prototype capacitive sensing applications. The onboard digital interface and range of adjustable options provide users with a great platform for prototyping, testing and validating the latest capacitive sensing technologies. With its advanced signal processing and calibration capabilities, the SX9500EVKA is an ideal platform for fast and accurate capacitive sensing design.
