2. Kit Operation
CY3280-MBR kit is designed to demonstrate four CapSense buttons and a CapSense based power
button.
Figure 2-1 illustrates these buttons: demonstration buttons (BTN0 to BTN3) and a CapSense
power button (POWER BUTTON). The kit is powered from two AAA on-board batteries, which are
placed below the kit in the battery holder. Configurable CapSense controller CY8CMBR2044
supports multiple features. The kit includes required hardware support to successfully demonstrate
each feature. See
Kit Features chapter on page 13 to know how to demonstrate each feature of the
CapSense controller using the kit.
The board has three connectors. Connector J5 can be used to demonstrate the SmartSense feature
and connectors J1 and J2 are used to provide external power to the kit and connect output signals
for CapSense controller to host systems.
Touch the power button first and ensure the power LED is turned on. Each CapSense button is
mapped to an LED (LED 0 to LED3) such that activation of each button can be verified visually by
monitoring the LED status. Active status of CapSense buttons are indicated by the ON status of the
LEDs.
