Connectors
This chapter describes the different connectors of the Demo Board. These are the RM connector
(X1, X2), the I/O connector (X5, X6, X7), the Programming connector (X3, X4) and the Power
connector (X8, X9, X10).
3.1
Radio Module Connector X1and X2
The Radio Module (RM) connector is an expansion header for the Adapter Board and its
soldered radio module. The RM connector consists of the two single row header X1
(RM connector 1) and X2 (RM connector 2). Both have 20 pins and a pin pitch of 2.0 mm.
The pinout of X1 and X2 is explained in Table 3-1 and Table 3-2.

Table 3-1: Pinout of X1
The pins X1.2, X1.3, and X1.4 are connected to the RS232 programming interface which is not
supported any longer. The pins X1.5, X1.6, X1.7, X1.9, X1.10 and X1.11 are connected to X4
which can be used for programming the WiMOD radio modules. All other pins of X1 are
connected to GND or to I/O connector 1.
