2 Interface Characteristics
ELS61-AUS is equipped with an SMT application interface that connects to the external appli-
cation. The SMT application interface incorporates the various application interfaces as well as
the RF antenna interface.
2.1 Application Interface
2.1.1 Pad Assignment
The SMT application interface on the ELS61-AUS provides connecting pads to integrate the
module into external applications. Figure 4 shows the connecting pads’ numbering plan, thE
following Table 1 lists the pads’ assignments.
