In the past, it was good manners to include a circuit diagram or sketches with every electrical device. We are happy to continue this tradition, because what we were able to learn from circuit diagrams back then has ultimately helped us all. The electronics of the new hörbert, recognisable by the V2.0 label, uses the ESP32 processor from Espressif. Many interfaces are led to the outside, so that we can offer extensions for hörbert in the future, as we have always done before. hörbert can be configured in detail with our playlist language PlaLa. We are constantly extending PlaLa with more commands.
