Hardware

The CY3280-MBR3 EVK is designed to demonstrate the features of the CY8CMBR3116 register-
configurable CapSense controller with four CapSense buttons and a proximity sensor loop. The kit
includes five sensor LEDs, which can be used to demonstrate the direct LED control feature of the
CY8CMBR3116. It also contains two LEDs to indicate power and kit status. The CY8CMBR3116
controller supports multiple features, which are discussed in 

. 

The CY3280-MBR3 EVK has two communication options: 

■

A USB interface for the USB-I

2

C bridge to communicate with the EZ-Click 2.0 customizer tool.

■

The I

2

C interface on the kit to connect to an external I

2

C host, for example, the PSoC 4 Pioneer 

Kit (CY8CKIT-042).

The CY3280-MBR3 EVK consists of the following blocks:

■

CY8CMBR3116 silicon

■

PSoC 5LP USB-I

2

C bridge

■

Power supply system

■

Four button sensors and one proximity loop

■

CY3280-MBR3 EVK LEDs: A power, status, and proximity LED and four CapSense LEDs

■

Capacitance variation demonstration

❐

Two-position slide switch to select long/short trace for BTN4

❐

Three-position slide switch to add capacitance on BTN2; the three positions of the slide switch 
correspond to 10 pF, 15 pF, and no additional capacitance

■

Arduino-compatible headers

■

Push button to reset the CY8CMBR3116

■

Buzzer, shield, and host interrupt pin multiplexing jumper

■

I

2

C selection jumpers to select between onboard PSoC 5LP and external host.
