AJMRTC TTP229 16-way capacitive touch switch module is a multi-channel digital touch sensor based on TTP229 chip. It can detect up to 16 independent finger touch points, replacing traditional mechanical keys to realize multi-touch input. The module uses I2C interface for data transmission, which is convenient to connect with Arduino, Raspberry Pi and other microcontrollers. Capacitive induction technology enables touch trigger without physical contact pressure. Onboard anti-interference circuit effectively reduces false trigger caused by external noise. It is suitable for smart control panels, custom DIY keyboards, interactive installation and various electronic development projects.
