The TTP224 4 Channel Capacitive Touch Sensor Module provides 4 independent capacitive touch inputs on a 35mm x 30mm PCB, operating from 2V to 5.5V, with a 0.5 second calibration delay at startup, built around the TTP224 Touch Switch chip. This ttp224 4 channel touch sensor’s 35mm x 30mm board footprint is a practical installation detail — it gives builders a predictable panel cutout or enclosure mounting dimension to plan around when integrating touch pads into a finished project enclosure.
The TTP224 module’s two selectable response modes offer a meaningful design choice: the 160ms low-power mode draws less current and suits battery-powered builds where power budget matters more than speed, while the 60ms fast mode suits mains-powered applications where snappier touch response improves user experience. Per the ttp224 touch sensor datasheet, the 0.5 second calibration window at power-up is when the chip measures and stores the baseline no-touch capacitance for each of its four channels individually.
this 4 channel ttp224 sensor’s fixed 35mm x 30mm board size and 4-pad layout means it works best when all four touch points are needed — projects only requiring one or two touch inputs might find the single-channel TTP223B a more compact fit. Available from StemVolt, well-suited for engineers and makers building panel-mounted touch interfaces and practical multi-button capacitive control electronics projects.
