Overview

The module is supplied with voltages  2.4 V to 5.5 V and contains sixteen capacitive buttons. It contains a LED to indicate power.

The advantage is the number TP229 module output lines: the module can deliver output using eight outgoing lines which allow us to check the status of the first eight buttons or serial communication line which can be used to read output via protocol via I2C.
