- The module is based on a touch-sensing IC (TTP223B) capacitive touch switch module. In the normal state, the module output low, low power consumption; 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 buttonsFeatures:
- 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

RGB LED module consists of a plug-in full color LED made by R, G, B three pin PWM voltage input can be adjusted Section three primary colors (red / blue / green) strength in order to achieve full color mixing effect. Control of the module with the Arduino can be achieved Cool lighting effects.
Specifications
- the use of plug-in full-color LED
- RGB trichromatic limiting resistor to prevent burnout
- through the PWM adjusting three primary colors can be mixed to obtain different colors
- with a variety of single-chip interface
- the working voltage: 5V
- LED drive mode: common cathode driver
