Primordial black holes might have existed in the early Universe and, via their evaporation mechanism (completed before Big Bang Nucleosynthesis), they might have released stable particles beyond the Standard Model. We discuss the possibility that such particles might constitute all or a fraction of the dark matter observed today, also considering the bounds on warm dark matter. If sufficiently light, stable particles from primordial black holes evaporation might provide a significant contribution to dark radiation.
