4.2 CAN Network Expansion
The AOA board even contains an on-board CAN network. There is a CAN node built around the
LPC11C24 microcontroller, which also contains an integrated CAN transceiver. The LPC1769 and
LPC11C24 processors communicates over the CAN network.
The CAN node can easily be detached from the main (LPC1769) board. If detaching the CAN node it is
recommended to first cut the board connection between the CAN node and the prototype area. After
that it is easier to cut off the CAN node. The location of the CAN network bridge is illustrated in the
picture below. When cutting the network bridge, be sure to check that there are no shorts between the
wires.
