    The breakout uses I2C communication interface to communicate with the microcontroller, it is able to set 4 different I2C device adresses for I2C. This means it is possible to use 4 of this brakouts to get max. 48 capacitive touch sensor inputs. It is also possible to adjust the senstivity when it is needed.

    It is possible to operate this breakout with both 3.3 V and 5 logic supply signals by the internal voltage regulator. This modul comes with 0.1 inch headers for simple mounting.

    Technical Features:

    • Dimensions: 33 mm x 19 mm x 2 mm
    • Weight: 2.2 gr
    • I2C device adress: 0x5A (possible to set as 0x5B, 0x5C and 0x5D)
