Product Overview

The CY3280-MBR3 is an evaluation kit designed to evaluate the performance of CY8CMBR3116 register configurable CapSense controller. It is also designed as an Arduino compatible shield that supports various Arduino baseboards as well as other stackable shields available in the market. The CY3280-MBR3 EVK has an onboard USB-I2C bridge to communicate with the EZ-Click 2.0 customizer tool, which configures the CY8CMBR116 controller. It offers the best features of Cypress CapSense in a small package that is easy to implement and configure. It is coupled with the Capacitive Sigma Delta PLUS (CSD PLUS) sensing algorithm and the patented SmartSense auto tuning feature. The CY8CMBR3116 controller provides a robust capacitive sensing solution with upto 16 CapSense inputs.
  • 4 CapSense buttons of two different sizes
  • LEDs corresponding to sensors indicating button touch
  • Pushbutton switch to reset the CY8CMBR3116
  • Shield electrode pin for water tolerance
  • I2C selection jumpers
  • Arduino compatible headers
  • Proximity loop and a corresponding LED to indicate proximity state (on/off)
  • Host interrupt pin
  • 2 slide switches to vary trace capacitance & demonstrate SmartSense auto tuning
