Xadow-Q Touch Sensor

21 ā‚¬21.00

Availability: Retired

The Q Touch Sensor is a high sensitivity and high noise immunity touch input device.It is based on Atmel AT42QT1070. The AT42QT1070 modulates its bursts in a spread-spectrum fashion in order to heavily suppress the effects of external noise, and to suppress RF emissions. The QT1070 uses a dual-pulse method of acquisition. This provides greater noise immunity and eliminates the need for external sampling capacitors, allowing touch sensing using a single pin.Ā  Ā  Ā  Specification Operating Voltage: 3 ~ 5.5VĀ  Operating Current @3.3V: 1mAĀ  Touch Keys: 7 Keys ; key0 ,key1 ,key2 are on the Xadow PCB bottom sideĀ  Communicating Protocol: I2CĀ  I2C Address: 0x1B Ā  Resource Q Touch LibraryĀ  Schematic pdfĀ  Eagle fileĀ  AT42QT107 datasheetĀ  How to detect finger touch Ā  Documents Please visit ourĀ wikiĀ pageĀ for more info about this product.
