The PSoC 4 Prototyping Kit is simplistic in design and focuses on providing you with complete
access to develop applications using the PSoC 4 device family. The development kit supports a
number of onboard functions such as an LED, push button, through-hole connections, USB-Serial
connectivity to the PC, and a breakable board design to separate the two target boards.
Figure 3-1. PSoC 4 Prototyping Kit
3.1 Connecting the PSoC 4 Prototyping Kit to a Computer
To use the PSoC 4 Prototyping Kit, you need to connect the kit to a target PC. The kit is designed to
be connected to the computer through USB. The USB connector will provide power to the target
boards and enable serial communication. CY8CKIT-049-4xxx implements a PCB-based USB
connector that makes connections to the USB port when plugged in. The amber LED turns on when
the board is plugged into the port to indicate power.

3.2 CY8CKIT-049-4xxx USB COM Port
Kit Operation
When you connect the CY8CKIT-049-4xxx to the PC over a USB interface, it enumerates as a COM
port device under the Device Manager window on the Windows OS. Often, the COM port number will
be higher than any existing COM port value. For example, in the following image the
CY8CKIT-049-4xxx enumerates as COM37.
Figure 3-4. CY8CKIT-049-4xxx USB COM Port in Device Manager
When connecting your CY8CKIT-049-4xxx to a computer for the first time or to any new USB port, it
may take a moment to enumerate because the computer will complete an online check for the latest
drivers.

Kit Operation
Figure 3-6. Driver Software Installation Complete
Note: The baud rate settings do not apply to the virtual COM port as the data transmission is taking
place using the Full-Speed USB bus at 12 Mbps. However, because of the virtual COM port driver
that sits between the PC and the USB-Serial device, the operating system will see the device as a
normal serial port and you will be able to set the baud rate. However, these settings may be ignored.
3.3 Programming a CY8CKIT-049-4xxx Project Using the Bootloader
The following example shows how to bootload (program) a project into the PSoC 4 with the
USB-Serial device, using the Bootloader Host. To use this method, the PSoC 4 device must contain
the bootloader and the project must be configured as bootloadable. This is the default programming
method for new users.
The following steps use the code example included in the kit installer.
1. Launch PSoC Creator from the Start menu.
