SparkFun Capacitive Touch Breakout - AT42QT1010

The AT42QT1010 SparkFun Capacitive Touch Breakout is a versatile and practical solution for integrating a user input interface without the need for a physical button. This product offers a single, momentary capacitive touch button that works seamlessly with digital I/O pins, making it an ideal choice for a wide range of projects and applications.

The AT42QT1010 is a dedicated, single-button capacitive sense chip. It monitors a conductive area for touch and maintains the output line high as long as a touch, such as from a finger, is detected. When no touch is detected, the line is kept low. The AT42QT1010 operates efficiently with a power source range of 1.8V to 5V. An additional PAD pin is available for those who wish to create their own external electrode.

What sets the AT42QT1010 apart is its internal time-out feature. After about 60 seconds of continuous touch, the board will turn itself off. This feature might be a game changer depending on the specific needs of your project. The AT42QT1010 is a slightly different version of the AT42QT1011, with minor differences that could significantly impact the functionality of your project.

The AT42QT1010 SparkFun Capacitive Touch Breakout is a user-friendly and adaptable solution for adding touch-based user input to your projects. Whether you're designing an interactive exhibit, a home automation system, or a custom game controller, this product is a reliable and efficient choice.
