2 Interface Characteristics
ELS31-VA/ELS51-VA is equipped with an SMT application interface that connects to the exter-
nal application. The SMT application interface incorporates the various application interfaces
as well as the RF antenna interfaces.
2.1 Application Interface
2.1.1 Pad Assignment
The SMT application interface on the ELS31-VA/ELS51-VA provides connecting pads to inte-
grate the module into external applications. Figure 3 shows the connecting pads’ numbering
plan, the following Table 1 lists the pads’ assignments.
