The distribution of elements on the keyboard.

Key features

  • It has 8 touch keys and 1 linear sensor.
  • The ability to work in a mode of 16 buttons - touch sensor provides additional 8 individual keys.
  • It communicates via the I2C bus, using only two lines: SDA and SCL, or in digital form - for each of the 8 buttons, a separate output OUTx.
  • The setting of the operation modes using jumpers.
  • It works with the voltage from 2.4 to 5.5 V.
  • It has an automatic re-calibration which activates itself when the keys are not touched for longer than 4 seconds.
