Hardware
The JTAG/SWD programming using J3 requires the programmer, which can be purchased from
Note While using MiniProg3, only Reset mode is supported with this Kit.

USB Communication
The board has a USB communications interface that uses the connector, as shown in
.
The USB connector connects to the D+ and D– lines on the PSoC to enable development of USB
applications using the board. This USB interface can also supply power to the board, as discussed in
applications using the board. This USB interface can also supply power to the board, as discussed in
Figure 4-6. USB Interface

Boost Convertor
The PSoC 5LP device has the unique capability of working from a voltage supply as low as 0.5 V.
This is possible using the boost convertor. The boost convertor uses an external inductor and a
diode. These components are prepopulated on the board.
This is possible using the boost convertor. The boost convertor uses an external inductor and a
diode. These components are prepopulated on the board.
To enable the boost convertor functionality, make the following hardware changes on the board.
■
Populate resistors R25, R27, R29, and R31
■
Ensure that R1 and R28 are not populated
After making these changes, you can configure the project to create a boost convertor-based design.
The input power supply to the boost convertor must be provided through the test points marked Vbat
and GND.
