Adafruit 1374 Standalone Momentary Capacitive Touch Sensor Breakout

Adafruit Standalone Capacitive Touch Sensor Breakout Momentary or Toggle – Adafruit 1374, The Adafruit Standalone Momentary Capacitive Touch Sensor Breakout boards operate without the need for a microcontroller using an AT42QT1010 sensor chip. When a touch is sensed, an on-board LED lights and the output pin goes high (logic 1), it goes low (logic 0) again when the touch is removed. You can save power by isolating the LED by cutting a trace on the board. It’s OK, the trace was specifically placed for just this reason and if you change your mind a small blob of solder will re-enable the LED. The chip is set to fast response mode which requires 0.5mA or you can set it to a slower mode that only uses 50µA by the same trace cutting trick used for the LED. You can also use your own touch pad by connecting it to a solder pad on the board. These are neat little boards with some interesting customisation options. Supplied as an assembled board plus a strip of 0.1in. header pins for you to solder on as required.Please note that these are logic level switches and not power switches.
