CenryKay TTP223B Capacitive Digital Touch Sensor Touch Button Module for Compatible Arduino10PCS

Specifications: Power supply voltage VCC: 2.0--5.5 V (Typical 3V) Output high VOH: 0.8VCC Output low VOL: 0.3VCC Output Pin Sink Current (@ VCC = 3V, VOL = 0.6V): 8mA 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: 2g Features: 1. Jog type: the initial state is low level, when touched by hand, S outputs a high level and the light is on; when the hand is released, it is a low level; if you touch S again, it outputs a high level, when the hand is released, it is low Level 2. Low power consumption 3.Power supply can be 2-5.5V DC 4. Both the front and back sides can be used as the touch surface, which can replace the traditional touch button 5.4 M2 screw positioning holes for easy installation Control interface: 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 lights up when it is right; Touch area: The area inside 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 hole diameter of 2.2mm, which are easy to install and locate the modules, and realize the combination between the modules Package Content: 10 * TTP223B Digital Touch Sensor Module
