The Human-Machine Interface (HMI) designs are in high demand, especially those requiring cost-effective touch sensing functionality. Adding capacitive touch to your embedded design is simple with the NXP's TWRPI-TOUCH-STR Tower Plug-In Starter Kit.

The NXP's TWRPI-TOUCH-STR Tower Plug-In Starter Kit is bundled as a complete set of four plug-ins, or snap-in components, the TWRPI-TOUCH-STR is designed to bring touch sensing to life in your Tower System designs. Simply place any combination of plug-ins from the Capacitive Touch Tower Plug-In Starter Kit onto a parent controller or peripheral module in the Tower System, and start prototyping quickly and easily. It's that simple, and quite literally, at your fingertips.  

• TWRPI-TSS: Touch sense TWRPI with pull-up resistors for use with MCUs running touch sense software (TSS) and interfacing to touch pad TWRPIs using GPIO signals
• TWRPI-MPR121: Touch sense TWRPI with NXP MPR121 touch sense controller. Manages touch interfaces to touch pad TWRPIs and communicates back to the host MCU via I2C.
• TWRPI-ROTARY: Touch pad TWRPI with a discrete, non-multiplexed rotary touch pad interface
• TWRPI-KEYPAD: Touch pad TWRPI with a classic 12-button keypad interface
