PSoC™ Creator hardware configuration
Infineon provides different development kits for the PSoC™ MCU families, including CY8CKIT-042 for PSoC™
4200, CY8CKIT-044 for PSoC™ 4200M, and CY8CKIT-046 for PSoC™ 4200L MCUs. Also available are low-cost kits
with a small form factor (prototyping kits), such as CY8CKIT-049 for PSoC™ 4200, CY8CKIT-043 for PSoC™ 4200M,
and CY8CKIT-147 for PSoC™ 4100PS MCUs.
These kits offer different features, but all include a user button and LED connected to the PSoC™ 4 MCU device.
You must make the appropriate pin assignments for each kit for the projects to function properly.

CY8CKIT-042 kit (PSoC™ 4200)
This kit includes a built-in debugger and connectors that are compatible with many common shield boards
compatible with Arduino. The most important feature of this kit pertaining to this application note and
measuring current is the power jumper, J13. To measure the current of the PSoC™ 4 MCU device, remove this
jumper and place an ammeter across the pins. By doing so, you are measuring only the current of the PSoC™ 4
MCU device and not the rest of the board. This board also includes the LED and the button required to exercise
these examples.
Another feature of the board is a USB-to-serial port adapter. By connecting a wire from PSoC™ 4 MCU P4[1] to
J11 pin 9, as shown in

the AN86233_DeepSleepADC project. The baud rate is 115.2 kbps, 8-bit data, and no parity. For more
information on using the USB-to-serial port feature, see the
