Adafruit 5-Pad Capacitive Touch Sensor Breakout AT42QT1070 1362

Description

Product Overview

The Adafruit AT42QT1070 breakout is a purpose‑built module that brings five independent capacitive touch pads to any project with minimal effort. Housed in a low‑profile PCB measuring just 3.6 × 2.6 × 0.2 inches and weighing only 0.16 oz, the board combines a compact mechanical design with a robust silicon sensor chip. The breakout includes all necessary passive components, a clear silkscreen layout, and a set of pin headers that make wiring to a microcontroller or single‑board computer straightforward. Powered by a 3.3 V supply, the sensor operates reliably across a wide temperature range and is fully compatible with Linux‑based platforms, allowing developers to integrate touch sensing into robotics, wearables, interactive art, and IoT devices without needing additional drivers.

Usage

Designed for makers, educators, and professional engineers, this breakout excels in environments where space is at a premium and reliable touch detection is essential. Whether you are building a custom keypad for a handheld controller, adding proximity awareness to a smart home appliance, or creating an interactive museum exhibit, the AT42QT1070 provides fast response times and adjustable sensitivity that can be tuned via I²C commands. Its five pads can be arranged in any configuration—linear, grid, or radial—making it adaptable to a variety of form factors. The module’s low power consumption also makes it suitable for battery‑operated projects, such as wearable health monitors or remote sensor nodes.

FAQ

What microcontrollers are compatible with the AT42QT1070 breakout?

The breakout works with any microcontroller that supports I²C communication, including Arduino, ESP32, Raspberry Pi, and many others. Sample libraries are provided for the most common platforms.

Can the sensitivity of each touch pad be adjusted?

Yes, the AT42QT1070 chip allows individual sensitivity settings via I²C registers, enabling fine‑tuning for different surface materials or environmental conditions.

Is the breakout suitable for outdoor use?

While the sensor itself is robust, outdoor installations should protect the board from moisture and extreme temperatures. Enclosing the module in a sealed housing will extend its lifespan in harsh environments.

How do I program the sensor on a Linux system?

Adafruit provides Python examples that use the SMBus library to communicate with the sensor. The documentation includes step‑by‑step instructions for setting up the I²C bus on Raspberry Pi and similar devices.

What is the warranty coverage for this product?

The AT42QT1070 breakout comes with a one‑year limited warranty covering defects in materials and workmanship. Support is available through Adafruit’s online help desk and community forums.
