ITEM NAME:TTP223B Digital Touch Sensor Capacitive touch switch module for Arduino 3C Specification: 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. 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 Specification: Item Min Typical Max Unit Power supply voltage VCC 2.0 3 5.5 V Output high VOH - 0.8VCC - V Output low VOL - - 0.3VCC V Output Pin Sink Current (@ VCC = 3V, VOL = 0.6V) - 8 - mA Output pin pull-up current (@ VCC = 3V, VOH = 2.4V) - 4 - mA Response time (low power mode) - - 220 mS Response time (touch mode) - - 60 mS Size 24x24x7.2 mm Weight 2 g Package Inclued: 1* Digital Touch Sensor capacitive touch switch module for Arduino.The module is based on a touch-sensing IC (TTP223B) capacitive touch switch module.
