1)
By default JP6 is shunted by a 0Ω resistor installed
at JS17.
2) To d3.3V to the tri-color led common anode,
remove the 0Ω resistor installed at JS17.

P1 10-pin SWD connector
– The SWD connector is used to
debug the LPC54102 Target from an external debug probe.
The same SWD connector can also be used to connect the
on-board Link2 debug probe to an off-board Target MCU
(for this JP1 must be shunted).

P2 LPC54102 VDD current monitor Vsense measurement. The
Vsense can be measured with a volt meter. Pin 1 (square
pad) is positive and pin 2 is negative. LPC54102 current is
calculated by dividing the measured voltage at P2 by the
Vsense resistance value of 8.2Ω. 5.1.1
P3
+5V External Voltage Input allows for powering the
LPC54102 Target side of the board from a bench-top power
supply. Pin 1 (square pad) is +5V and pin 2 is gnd. 5
SW1 LPC54102 Target WAKEUP pushbutton. When pressed the
WAKEUP switch will drive LPC54102 P0_24 to a low level. 9.3
SW2 LPC54102 ISP Bootload enable pushbutton. This switch
drives LPC54102 P0_31 low. Holding SW2 pressed while
powering up or reseting and the LPC54102 Target will enter
ISP mode. 9.2

3. Getting Started
By default, the LPCXpresso54102 is configured to use the on-board debug probe (Link2)
to debug the on-board target (LPC54102), using the CMSIS-DAP debug protocol pre-
programmed into the Link2 Flash memory. The LPCXpresso IDE (available for free
download at
http://www.lpcware.com/lpcxpresso/home ) or development tools that
support the CMSIS-DAP protocol can be used in the default configuration. Check with
your toolchain vendor for availability of specific device support packs for the LPC54100
family of devices. (Note that the LPCXpresso IDE can also be used with redlink protocol
by booting the Link2 in DFU mode, by installing a jumper on JP5.)
Installation steps for use with LPCXpresso IDE (steps 1 and 2 apply to all use tool
chains):
