7.5 Expansion connectors (including Arduino connectivity)
The LPCXpresso546x8/540xx/54S0xx board includes four expansion connectors (J9,
J10, J12 and J13) incorporate an Arduino Uno revision 3 footprint in their inner rows.
These connectors provide access to the CAN interfaces, additional digital microphone
support signals, I

S, I

C, USART, SPI and GPIO/INT/PWM connections. Note that
several of the signals available at these connectors are shared with other connectors or
board functions, so may not be usable if those other functions are being used.
Table 6 shows the connector circuit references and purposes.

Description
J9
The odd number pins are compatible with Arduino Uno rev3 Digital 15:8,
AREF, SDA & SCL connector. The even numbered pins are used for
external access and expansion of LPC546x8/540xx/54S0xx signals not used
by the Arduino Uno rev3 compatible interface.
J13
The odd numbered pins 1 – 15 are compatible with Arduino Uno rev3 Digital
7:0 connector. The even numbered pins, and odd numbered pins 17 and 19,
are used for external access and expansion of LPC546x8/540xx/54S0xx
signals not used by the Arduino Uno rev3 compatible interface.
J10
The even numbered pins 6 – 20 are compatible with the Arduino Uno rev3
Power connector standard.
On Revision E and later boards, pins 13 and 15 are used to provide access
to Smart Card 0 port (board modifications required to use this feature – see
Section 7.7.
J12
The even numbered pins 2 – 12 are compatible with Arduino Uno rev3
Analog connector. The odd numbered pins are used for external access and
expansion of LPC546x8/540xx/54S0xx signals not used by the Arduino Uno
rev3 compatible interface.
