TTP224 4-Channel Digital Touch Sensor Module Capacitive Switch Button for MCU

Description

This is a 4 switch digital touch sensor with capacitive sense technology, the TTP 224 IC offers capacitive sense input feed designed for touchpad control, followed by a 4- finger-sized touchpad. The board has a jumpers arrangement to change the keypress 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 microcontroller 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 Arduinos board. The board finds applications in HMI(Human-machine Interface), mechanical Button key replacement.

Note : HW-138 on board working remains same.
