Hardware
4.3.1.1 Measure PSoC 4 Current Consumption
You can measure the current consumption of the PSoC 4 device by using one of these methods:
Method 1:
1. Separate the USB-Serial board by 'snapping' the perforated edge between the two boards.
2. Power the remaining prototyping board via any of the VDD terminals.
3. Place an ammeter in series with the VDD connection to measure the current consumption.
Method 2:
1. Remove the resistor R6 and install a 2-pin jumper in the supplied holes of J4.
2. Connect an ammeter across the 2-pin jumper to measure the current to the PSoC 4 device.
This method can be used either with USB power or with power supplied to one of the VDD pins.
4.3.2 Board Separation (Snapping)
CY8CKIT-049-4xxx supports both the PSoC 4 and USB-Serial boards. To separate the two boards
for testing or development, break the two boards apart at the built-in perforated edge.
The easiest method of separating the two boards is to place the kit on the edge of a table, where the
edge of the table is directly below the perforated edge and the smaller USB-Serial device is off the
table edge. Press gently on the USB-Serial board and snap the two boards apart. If any material is
removed from the edge of the boards, use sheers to clean up the edge of the kit.

4.3.3 Header Connections
The CY8CKIT-049-4xxx Prototyping Kit supports a number of unpopulated headers on both the
USB-Serial and the PSoC 4 boards.
