Smart Electronics TTP223 TTP223B Jog digital touch sensor capacitive touch touch switch modules Accessories

The module is a capacitive touch switch module based on touch detection IC (ttp223b). Under normal condition,
the module outputs low level and the mode is low power consumption mode; when touching the corresponding
position with fingers, the module outputs high level and the mode switches to fast mode; when there is no touch
for 12 seconds, the mode switches to low power consumption mode. The module can be installed on the surface
of non-metallic materials such as plastic and glass. In addition, a thin piece of paper (non-metal) can be covered
on the surface of the module. As long as the touch position is correct, it can be made into buttons hidden in the wall,
desktop and other places. The module allows you to avoid the fan of the conventional press button.

The features of the module are as follows:Module features are as follows
Inching type: the initial state is low level, touch is high level, non-touch is low level
(similar to the function of tapping the key)
Low power consumption
The power supply can be 2~5.5VDC
Both front and back sides can be used as touch surfaces, which can replace traditional touch buttons
4PCS M2 screw positioning holes for easy installation

Control connection: a total of 3 pins (GND, VCC, SIG), GND is the ground, VCC is the power supply,
and SIG is the digital signal output pin.
Power indicator: Green LED, it will light up when it is powered on correctly.
Touch area: the inner area of the icon similar to a fingerprint, which can be triggered by a light touch of a finger.
Positioning holes: 4 M2 screw positioning holes with a diameter of 2.2mm, which make the module easy to
install and position and realize the combination between modules.
