Digital capacitive touch keypad module

Model: TIP229.
Digital capacitive touch keypad module.
This is a semiconductor-based touchpad that is a reliable alternative to classic keyboards with switches. This capacitive touch sensor module has the TTP229 IC with sensitive touchpads that are an excellent replacement for the old-fashioned keypads. Module Capacitive touch allows sensing when a finger is within a few millimeters. We may use capacitive sensing in any place where low to no force of human touch sensing is needed.
Features:
16-channel maximum touch key sensing
Operating voltage – 2.4 V – 5.5 V for built-in regulator mode.
Operating voltage – 2.0 V – 5.5 V for built-in regulator disabled.
Inbuilt regulator for touch sensors.
Operating current 2.5uA typically in 16-key mode. Operating current 2.0uA for 8-key mode.
I2C enabled for communication with host.
Adjustable sensitivity using an external capacitor (1-50 pF)
Stable touch detection of the human body.
All output modes can be configurable for high or active low by pad options.
