Overview

The CapTIvate™ button, slider, wheel, and proximity demonstration board is an evaluation platform for self-capacitance touch sensors in a variety of configurations. The sensor panel demonstrates low power design principles and showcases MSP430™ CapTIvate MCU's wake-on-proximity state machine feature. The panel board also demonstrates the high slider and wheel sensor resolution achievable with self-capacitance sensors.

  • Interfaces to MSP430 CapTIvate ecosystem MCU boards, such as the CAPTIVATE-FR2633
  • 16 capacitive touch elements, including 8 buttons, one 3-element wheel, one 4-element slider, and one proximity sensor
  • Wake-on-proximity operation with 5µA average current

  • CAPTIVATE-BSWP sensor board
  • CAPTIVATE-PGMR not included; CAPTIVATE-PGMR is required for tuning and programming
  • CapTIvate MCU Board (i.e. CAPTIVATE-FR2633 or CAPTIVATE-FR2676) not included
