miniDSP UMA-16 v2 Mic Array
The UMA-16 v2 is the updated version of our sixteen-channel microphone array with plug&play USB audio connectivity. With its onboard XMOS interface, the UMA-16 is the perfect fit for the development of beam-forming algorithms or your DIY acoustic camera. Its system architecture consists of two core elements:
- A microphone PCB with 16 x Knowles PDM MEMS microphones in a uniform rectangular array (URA). A center hole fits an optional USB camera for applications such as acoustic cameras. The microphone PCB is a simple 2-layer design that can easily be customized to your needs by following our schematics included in the user manual.
- Stacked on top of the mic array is the MCHStreamer Lite USB interface. This XMOS XCORE interface allows for a high quality PDM to PCM conversion and presents all 16 channels of raw audio to the USB interface.
Features
- Multichannel USB microphone array for voice command
- 16 channels of RAW audio for development of custom beamforming algorithms
- High quality MEMS from Knowles SPH1668LM4H
- USB to PDM conversion for up to 16 x PDM MEMS microphones
- Center Hole for USB camera (Not provided)
- Sample Matlab code to get started
