Arduino interface
C211 boards contain an Arduino compatible interface that can be used to connect, for example, an
ODIN-W2 EVK to enable wireless communication over UDP. For further information about UDP, see
the u-connectXpress software user guide [16].
The Arduino connectors, J1, J3 and J4, are shown in Figure 9.
