Description

Description:

Both of these modules are based on a touch-sensing IC TTP223 capacitive touch switch module.

These allows you to avoid the trouble of conventional push-type buttons.

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

Touch Sensor Interface :

-Control Interface : A total of three pins (GND, VCC, SIG), GND to ground , VCC is the power supply , SIG digital signal output pin.

-Power Indicator : Green LED, power on the right that is shiny.

-Touch area : Similar to a fingerprint icon inside the area , you can touch the trigger finger.

-Positioning holes : 4 M2 screws positioning hole diameter is 2.2mm, the positioning of the module is easy to install , to achieve inter- module combination.
