The ReSpeaker Core v2.0 allows developers create powerful and impactful voice and sound interfaces. Suitable to use as a base for smart assistance as well as responding to environmental sounds, the ReSpeaker Core v2.0 was designed with the idea that developers deserve to have many options available to them.

We received much feedback from ReSpeaker Core v1 users and have added many requested features. Different from the original board this SBC is running Debian* with an onboard microphone array and software based voice enhancement algorithms.

A High Performance Platform

The ReSpeaker Core v2.0 is powered by the Axol Core module, featuring the Rockchip RK3229 Quad-Core Cortex-A7 with a Mali 400MP GPU, 1GB of DDR3 RAM, and a PMU. The core runs the Debian OS. This provides developers with much more flexibility and resources to create their projects.

Around the core are peripherals including a Kingston 4GB eMMC to enable the OS to run onboard, a WiFi/BLE module, USB, Grove, and HDMI connectors, the on board 6-mic array, LED ring, and more.

An Onboard 6-Mic Array with Professional Voice Enhancement Algorithms

New in our ReSpeaker product line is a software based approach to voice enhancement. The more powerful Axol Core allows the Core v2.0 to process the audio received through the 6 far field microphones in real-time. The ReSpeaker Core v2.0 supports Noise Suppression (NS), Keyword Wakeup, Direction of Arrival (DoA), Beam-forming (BF), Acoustic Echo Cancellation (AEC). Our BF and AEC algorithms are provided by Alango , a professional audio DSP company used in the automotive industry.

An Open Software Ecosystem

We recognize that each project has different requirements and goals. As such we have worked to provide as much flexibility to developers as possible. Our quad-core solution allows us to run numerous software solutions. From the selection of algorithms, NLP services, smart assistants, operating systems, and more, we wish to support our users. If you have suggestions on what services you would like to see us officially support let us know on our forums, or if you enjoy the work yourself, submit a merge request to our github.

Audio and Video Output*

Audio output is available via the 3.5mm audio jack (output only), as well as a JST two pin connector and Bluetooth. The ReSpeaker Core v2.0 supports video output through HDMI* enabling developers to create rich visual interfaces to pair with a voice interface.

Mixed Results - Sauberkugel Clean Ball Review
Color: Bag Petrol
I purchased the Sauberkugel Clean Ball in Teal to help keep my bags clean from dust, dirt, and crumbs, and while it had some positive aspects, I can only give it a moderate 3-star rating due to a few shortcomings. On the plus side, the concept of the sticky inside ball is ingenious and showed promise. It did manage to pick up some dust and small particles (including glitter) from my purse which was a relief. The teal color is cute and made it easier to spot in a bag. However, there were some limitations that affected its overall effectiveness. *It seemed to struggle with picking up certain types of debris, particularly larger crumbs, heavier dirt, and ever some larger glitter/confetti pieces. This inconsistency was a bit disappointing as I had hoped based on the ads for it to be much more effective. *Another major issue I encountered was the difficulty of opening and cleaning the ball. The design was supposed to make it relatively easy to open and clean (as the ads lead me to believe). However I was unable to get the ball unlatched - which made it quite challenging to clean fully. It was frustrating to wrestle with the ball and being unable open to clean it out fully. In summary, while the Sauberkugel Clean Ball had its merits and did manage to capture some unwanted particles, it fell short in terms of consistency and ease of use. The struggle to open and clean the ball was a significant drawback for me.

Great item, totally worth it.
Color: Black
I've used this for over a year now in my nice work purse to keep those tiny dirt particles from who-knows-where (you know the ones I mean!) from mysteriously getting in the bottom of of it. It rolls around easily in its plastic case either naturally (without getting goopy or leaky) or rolled by hand. Handiest thing I've ever bought to help keep my purse clean!
