TTP223 Capacitive Touch Key Module The TTP223 Touch Key Module is based on a touch-sensing IC (TTP223) capacitive touch switch module. A capacitive touch sensor module based on the dedicated TTP223 touch sensor IC. The module provides a single integrated touch sensing area of 11 x 10.5mm with a sensor range of ~5mm. An onboard LED will give a visual indication of when the sensor is triggered. When triggered the output of the module will switch from its idle low state to high (default operation). Solder jumpers allow for reconfiguring its mode of operation to be either active low or toggle outpu t. TTP223 Capacitive Touch Sensor Module. The TTP223 is a touchpad detector IC replicating a single tactile button. The TTP223 is a touchpad detector IC replicating a single tactile button. This touch detection IC is designed for replacing traditional direct button key with diverse pad size.

TTP223 Jog Digital Capacitive Touch Sensor Module is a high-quality electronic component designed for Arduino, prototyping, and educational electronics. TTP223 Jog Digital Capacitive Touch Sensor Module The module is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the module output low, When a finger touches the corresponding position, the module output high, if not touched for 12 seconds, switch to low-power mode. Jog type : the initial state is low , high touch , do not touch is low ( similar touch of a button feature ) Module can be installed in such as surface plastic, glass of non-metallic materials. In addition to the thin paper ( non-metallic ) covering the surface of the module , as long as the correct location of the touch , you can make hidden in the walls, desktops and other parts of buttons. Features: Low power consumption Power supply for 2 ~ 5.5V DC Can replace the traditional touch of a button Four M2 screws positioning holes for easy installation. Size 24x24x7.2 It’s perfect for DIY makers, students, and anyone building custom electronic circuits or STEM kits.
