Expansion Connectors

There are two expansion connectors, J1 and J2. They both have 15 positions and are placed at the

board edges. See

Figure 2

on page 13 for details about J1 and J2 placement on the board. All

programmable pins of the LPC1343 are available on the expansion connectors; see the table below for

details.
