The SENS-TTP224 is a 4-channel digital touch capacitive sensor module.  

TTP224 is a 4 switch digital touch sensor with capacitive sense technology, the TTP 224 IC offers capacitive sense input feed designed for touch-pad control, followed by a 4- finger-sized touch-pad. The board has a jumper’s arrangement to change the key press output mode in Timed or Toggle, Active High or Active Low. Separate jumper adjustments are provided for changing the response time of the pressed key: 60mS fast mode or 160mS in Low power. The output side of the board has 6 pin headers, with 4 pins to be connected with the digital I/O of any micro-controller board (Arduino, ARM STM32). 4 status LED SMD types are provided to check the status of each pressed key. TTP 224 4 Channel Digital Touch Sensor is compatible with all Arduino’s board. The board finds applications in HMI (Human-machine Interface), mechanical Button key replacement.

Features:

4 key board TTP224 capacitive touch sensor IC
Onboard 4-level status indicator
Operating voltage: 2.4V-5.5V
Module can set the output mode, the key output mode, the longest time and fast output / low power option.
PCB board size: 35 (mm) x 29 (mm)

Trigger setting mode:

  • (1- > Short ; 0- > No Short)

  • AB=00: No-lock High TTL level output;

  • AB=01: Self-lock High TTL level output;

  • AB=10: No-lock Low TTL level output;

  • AB=11: Self-lock Low TTL level output;

Specification:

  • IC: TTP224 4 Channel; Jog type: the initial state is low, high touch, do not touch is low (a similar touch of a button feature) Low power consumption

  • Power supply: 2 ~ 5.5V DC; 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;

  • Touch surface can be used as positive and negative, can replace the traditional touch of a button

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

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