embidio Hub

Optimized solution for your prototype development

Take advantage of the modular hardware of the embidio Hub and reduce the development time of your smart products by 10 times. Each module has integrated signal processing and pre-programmed beamforming, so you can focus on the essentials – we take care of the reliable voice control.

Due to its small dimensions and freely selectable positioning of the microphones, it offers maximum flexibility in integration. Thus, even with little space your project can be implemented. The audio recording is supported by 2 and up to 8 microphones. Thus, clear recordings can be realized even in loud and rough environments.

embidio Hub

Easy to integrate

embidio Hub offers ideal conditions for the first prototyping due to its numerous interfaces and the freely selectable microphone configuration.

Various interfaces offer the possibility to test the audio module and to connect it to your existing products and systems, which already have their own user interface, such as display or buttons, and voice processing.

With USB connectivity, the embidio Hub is ready to go and enables multi-channel recording and playback on Windows, Linux and MacOs OS.

Thanks to numerous software modules, the hub can be adapted to your applications and enables voice interactions with the voice assistant even in noisy environments.

Up to 56% reduced costs

The embidio Hub is pre-configured and Ready to Use for a direct start into the product development of your smart products with reliable voice control.

The compact product dimensions of 53mm x 67mm and the low weight of 19.9gr make embidio Hub a universal tool for producers of innovative product lines.

It is compatible and expandable at any time with all embidio hardware products.
