4.18 SP10: CAN

The CAN interface is not supported since there is no on-chip CAN peripheral on the LPC3250.

For reference, the information about the interface is described below.

There is one CAN interface mounted on the board. The board is also prepared for a second CAN

interface, if needed. Via JP16 it is also possible to add termination resistors, if needed. The interface

has on-board ESD protection.

See picture below for locating relevant components. The table below lists signal connections.
