7-point touch sensor

Description

The modules are used to operate 7 touch fields. This is possible thanks to the built-in AT42QT1070 capacitive touch sensor. The derived I2C interface serves for communication.

The power supply voltage is 1.8 to 5.5 V. The tactile field should be at least 6 x 6 mm. It may have different sizes and shapes, depending on the thickness of the touch panel, which may be plastic, glass or plastic. Detailed recommendations on the touch field can be found in the AT42QT1070 datasheet.

There is also a module that supports 5 touch boxes with 1/0 output instead of the I2C interface.
