TTP226 Capacitive Touch Module

TTP226 TonTouchTM is a contact plate detection (touch pad detector) IC, providing eight touch keys. Meet Touch detection IC intends to replace the traditional fixed-size direct button key pad. Low power consumption and wide operating voltage is in contact with key DC AC applications or features. This capacitive touch sensor module uses the TTP226 integrated circuit, making it easy to add capacitive touch input to your project. It features 8 sensitive touch pads that make an ideal replacement for the old fashioned switches. The TTP226 capacitive touch sensor module is perfect for adding 8 capacitive touch inputs to your new project.
