  The characterisation of detached eclipsing binaries with low mass components
has become important when verifying the role of convection in stellar
evolutionary models, which requires model-independent measurements of stellar
parameters with great precision. However, spectroscopic characterisation
depends on single-target radial velocity observations and only a few tens of
well-studied low-mass systems have been diagnosed in this way. We characterise
eclipsing detached systems from the {\it Kepler} field with low mass components
by adopting a purely-photometric method. Based on an extensive multi-colour
dataset, we derive effective temperatures and photometric masses of individual
components using clustering techniques. We also estimate the stellar radii from
additional modelling of the available {\it Kepler} light curves. Our
measurements confirm the presence of an inflation trend in the mass-radius
diagram against theoretical stellar models in the low-mass regime.
