Datasheet

any digital I/O pin. In the library example code you can set up that pin in the CAP1188 object

creation.

If you're using multiple sensors, or you just want to change the I2C address to something

else, you can choose from 5 different options - 0x28, 0x29 (default), 0x2A, 0x2B, 0x2C

and 0x2D

The I2C address are selected by connecting a resistor to the AD pin in the lower right:

different resistors set a different address. The easiest address to set is 0x28 which is just a

wire from AD to the 3Vo pin.
