Fig 8. CAN-FD Shield Layout
The CAN-FD Shield has a double-height DB9 connector installed by default (P3) for
CAN/CAN-FD connections.
The Shield board layout includes provision for a DB9 connector to be installed (P2) but a

RS232C transceiver CTS connection.
When fitted, the RS232C transceiver CTSn signal is connected
to expansion connector J4 pin 8 (Arduino A4). On the
LPCXpresso546x8/540xx/54S0xx boards A4 is connected to pin
PIO3_4; this pin is shared with the accelerometer interrupt
output.
RS232C transceiver RXD connection.
When fitted, the RS232C transceiver R1OUT signal is connected
to expansion connector J2 pin 20. On the
