TTP229 16 KEY CAPACITIVE TOUCH KEYPAD MODULE IN PAKISTAN
TTP229 Capacitive Touch Module is can replace conventional 4×4 keypad with a touch based keypad. The module has two working modes. A 8 key mode that provides a independent 8 channel output or a 16 key mode that can be used with the I2C interface of the module, there by saving even more pins and connections on the application Arduino or Microcontroller board.Sensitivity can be adjusted by the capacitance(1~50pF) outside.
