  We study the Su-Schrieffer-Hegger model, perhaps the simplest realization of
a topological insulator, in the presence of an embedded impurity superlattice.
We consider the impact of the said impurity by changing the hopping amplitudes
between them and their nearest neighbors in the topological boundaries and the
edge state localization in the chain of atoms. Within a tight-binding approach
and through a topolectrical circuit simulation, we consider three different
impurity-hopping amplitudes. We found a relaxation of the condition between
hopping parameters for the topologically trivial and non-trivial phase boundary
and a more profound edge state localization given by the impurity position
within the supercell.
