  We examine - both experimentally and numerically - a two-dimensional
nonlinear driven electrical lattice with honeycomb structure. Drives are
considered over a range of frequencies both outside (below and above) and
inside the band of linear modes. We identify a number of discrete breathers
both existing in the bulk and also (predominantly) ones arising at the domain
boundaries, localized either along the arm-chair or along the zig-zag edges.
The types of edge-localized breathers observed and computed emerge in distinct
frequency bands near the Dirac-point frequency of the dispersion surface while
driving the lattice subharmonically (in a spatially homogeneous manner). These
observations/computations can represent a starting point towards the
exploration of the interplay of nonlinearity and topology in an experimentally
tractable system such as the honeycomb electrical lattice.
