8.3 Host Expansion Header (J14)
This header provides connectivity from the LPC54S018J4M target to a remote Host,
peripherals or other devices.
Table 4 shows the connections.

12 VDD (3.3V)
This connector shares SPI interface signal connections with the SPI bridge function (i.e.
connection from the LPC54S018J4M to the Link2 Debug Probe); only one of these
functions may be used at once. By default jumper JP6 is open, connection the Flexcomm
3 SPI port to the Link2 device; install JP6 if using the SPI port on J14.
By default, solder jumpers JS15 and JS16 connect the LPC54S018J4M Flexcomm 1 I

port to the Link2 device; these may be removed if they will interfere with other devices
interfaced to J14. Note there are 2.2KΩ pull-up resistors to 3.3V for these SDA and SCL
connections.
8.4 PMod Slave Expansion Header
This header provides connectivity from the LPC54S018J4M target to PMod peripherals
or other devices.
Table 5 shows the connections.
