CMU TOUCH PAD BOARD

SKU: CMU TOUCH PAD BOARD

BRAND: Communica


Touch Pad Board Touch to TTL Signal 3,3-5VDC

Overview

Features

  • 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 buttons
  • 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
