Standalone 5-Pad Capacitive Touch Sensor Breakout - AT42QT1070

This breakout board provides an easy solution for projects requiring multiple capacitive touch sensors. No microcontroller is necessary—just supply power between 1.8 to 5.5VDC and connect up to 5 conductive pads to the 5 pins on the left-hand side. When a capacitive load (e.g., a touch) is detected on one of the pads, the corresponding LED on the right will light up and the output pin will go low. This can be used to replace standard buttons in projects where pressing a button connects it to ground.

Note that the board is designed to detect only one contact at a time to prevent multiple touches from triggering at once, offering protection from accidental brushing of multiple pads.

The kit comes fully assembled and includes a stick of 0.1" header pins for easy integration into a breadboard. For the conductive contacts, it is recommended to use copper foil, with a wire soldered from the foil pad to the breakout.

The datasheet provides detailed information on sensitivity, power consumption, and other specifications. It's important to note that this board operates in 'standalone' mode only and does not support I2C mode.
