embidio Nano

Ideal for series production of new innovative smart products.

The NextGen processor and the compact design of the embidio Nano provide universal and reliable voice assistance and are therefore ideal for new developments. The embidio Hub allows you to test possible applications of voice assistance beforehand and to adapt the system to your needs and validate it in pilot tests.

embidio Nano

Ready for the crowd

The compact and powerful embidio Nano is easy to integrate and enables cost-effective series production with its wide range of functions.

Due to its small dimensions, it is easy to integrate and offers numerous interfaces for recording with up to 8 microphones, as well as stereo playback via loudspeakers. Visual and hardware-based security functions can be realized through the connections for LEDs and buttons. In combination with our development kit embidio Hub, the embidio Nano can be individually adapted to the target application by software modules.

Up to 77% more flexibility

The minimal design of embidio Nano and the innovative technology ensure universal start of serial production and flexible use for any targeted product. With dimensions of only 24mm X 50mm and a low weight of less than 10g, the voice module can be integrated into even the smallest products.

The embidio Nano is compatible with all embidio hardware products and can be extended with the conhive Dashboard at any time.
