AT42QT1070 HiLetgo Capacitive Touch Sensor Breakout with 5 Pads

Description

Product Overview

The HiLetgo AT42QT1070 breakout module is a highly integrated, standalone capacitive touch sensor designed for developers who need reliable touch detection without the complexity of external communication protocols. Built around the proven AT42QT1070 chip, the board features five individually addressable conductive pads that can be configured for a wide range of touch‑sensing applications. Its compact 2 × 2 inch footprint (approximately 5 × 5 cm) and ultra‑thin 0.01‑inch profile make it easy to embed into tight enclosures, while the low‑power design (typical current draw under 1 mA in active mode) ensures long battery life for portable devices. The module is supplied with a standard 0.1 mm pitch breakout, providing easy soldering and straightforward connection to common development platforms such as Arduino, ESP32, and Raspberry Pi Pico.

Usage

Designed for a broad spectrum of projects, the AT42QT1070 breakout excels in wearable technology, smart home interfaces, interactive art installations, and educational kits. Its five‑pad layout allows designers to create multi‑button input panels, gesture‑based controls, or even simple proximity detectors for robotics. Because the sensor operates in a fully standalone mode, it does not require an I²C or SPI bus, reducing wiring complexity and freeing up microcontroller pins for other functions. Whether you are building a prototype for a new fitness tracker, a touch‑enabled lamp switch, or a classroom experiment on capacitive sensing, this module provides a plug‑and‑play solution that can be powered directly from 2 V to 5.5 V, making it compatible with most low‑voltage development boards.

FAQ

Can the AT42QT1070 be used with I²C communication?

No. This breakout is configured to operate only in standalone mode, which means it does not expose an I²C interface. All touch processing is handled internally by the chip.

What is the typical power consumption of the sensor?

In active mode the module draws less than 1 mA, and in standby mode the current drops to a few microamps, making it suitable for battery‑powered applications.

How many touch events can the sensor detect simultaneously?

The AT42QT1070 can detect up to five simultaneous touches, one on each pad, allowing for complex multi‑touch gestures.

Is the breakout compatible with 3.3 V logic levels?

Yes. The module operates from 2 V up to 5.5 V, so it works perfectly with 3.3 V microcontrollers and logic circuits.

Do I need any additional components to use the sensor?

Only a power supply and a ground connection are required. The breakout includes all necessary pull‑up resistors and capacitors for stable operation.
