Simply supply 1.8–5 V and ground — the chip handles all touch monitoring and outputs a digital high signal when a touch is detected, low when released. Unlike the AT42QT1010, this variant has no internal time-out, meaning the output stays high for as long as a touch is held. A PAD pin is broken out for connecting an external electrode to create custom touch surfaces. Key Features Single Capacitive Touch Button – Momentary digital output (high when touched) No Time-Out – Output remains high for the full duration of a touch Wide Voltage Range – Operates from 1.8–5 V External Electrode Support – PAD pin for custom touch surfaces Simple Digital I/O – No library or complex setup required Specifications IC – AT42QT1011 Operating Voltage – 1.8–5 V Output – Digital high (touched) / low (released) Time-Out – None (output held indefinitely during touch) Ideal For Button-free user interfaces Interactive art and installations Proximity-triggered projects (with external electrode modification) Arduino and microcontroller input Package Contents 1× SparkFun Capacitive Touch Breakout (AT42QT1011) Tip: For proximity sensing (triggering without direct contact), try replacing the 10 nF capacitor at C2 with a 100 nF capacitor and using an external electrode.
