3.2 Powering the Board
The LPC1768-Xplorer can be powered through USB port. It is highly recommended that the user tests
all the peripherals as soon as the board is received. A regulated supply can be supplied to the 5V pin on
the Xplorer-LPC1768 header.
Note: The USB power can source only up to 500 mA of current. For applications having higher current
requirements we recommend to use an external power supply. Please note that the external power
supply is not a part of standard delivery.
3.3 Verifying all the peripherals on LPC1768-Xplorer
The following section focuses on the verification of all the peripherals supported on the LPC1768-
Xplorer. The order of the tests is mentioned in the same manner as the flow of the test firmware. We
highly recommend that you follow the order of the test. The test firmware is designed in a manner that
the user needs to spend as minimum time as possible to verify all the on-board peripherals. The test
firmware executable resides on the Flash.
Note: The test firmware “Debug Messages” or flow might be changed in due course. Generally these
are only cosmetic changes so that the usage is easier. If you observe a different message than the one
mentioned in the Manual, do not worry and please proceed with the test
Power up the board over USB port and we are all set to verify the LPC1768-Xplorer peripherals. Before
we get to the verification we need to install the Virtual COM port drivers needed for the LPC1768-
Xplorer (USB port) to appear as a Virtual COM port (Used for viewing the debug messages on serial
emulation tool). Fortunately, this is a one-time setup and fairly simple. On a Windows machine the user
needs to point to the location of the INF file (the INF file can be found in the download folder provide
on product registration; the path for INF file is:
(LPC1768_Xplorer_LPCXpresso\LPC1768_Xplorer_usbVcom_lib
).
