Libre Wireless Technologies Single Chip MAVID Solution is Now Amazon AWS IoT Core Certified

April 28 2020, 01:15
Libre Wireless Technologies, the embedded wireless audio and voice/AI development platform company, announced that its MAVID low power mic-to-cloud edge computing solution expanded its unique RTOS platform to include new SDK releases. The company's flexible SDK for connected devices now features Amazon AWS IoT Core certification and leverages the responsive Free RTOS operating system, combined in a scalable feature rich platform. The new development environment offers unique connectivity and libraries for manufacturers and ODMs developing on Libre Wireless's MAVID platform. 
 

Libre Wireless' MAVID (Multi-protocol Audio Voice IoT Device) is a super compact, ultra-low power mic-to-cloud platform with support for Alexa Voice Service (AVS) and AWS IoT Core. With this latest expansion, MAVID is now even better suited to address broader applications with connected products that can leverage this highly integrated low power solution, going well beyond the initial release of the Libre Wireless platform which featured a complete Alexa Built-In voice assistant and media streaming feature set.

The MAVID device, a single chip mic-to-cloud solution measuring only 13.5mm square, offers developers the opportunity to take their connected audio and Alexa-enabled projects into even more applications. Working closely with Amazon, Libre has delivered a certified Amazon AWS IoT Core SDK that offers full cloud connectivity features and can utilize Libre’s own AWS cloud or connect to a manufacturers own cloud system. The SDK offers development environments in both IAR and GCC. 

The certified Amazon AWS IoT Core SDK enables devices to connect, authenticate, and exchange messages with AWS IoT Core using the MQTT, HTTP, or WebSockets protocols. The AWS IoT Device SDK supports C, JavaScript, and Arduino, and includes the client libraries, the developer guide, and the porting guide for manufacturers.

More details of this new solution from Libre Wireless are available directly from the Amazon AWS Partner Device Catalog web page, covering both the MAVID Device as well as the related EVK GBS Minitower development platform. The solution enables OEMs and ODMs to create entirely new applications such as pocket-sized battery-powered devices as well as portable and even wearable designs for next generation AI and voice service products.

While measuring only 13.5mm x 13.5mm, MAVID delivers performance optimized dual-band Wi-Fi connectivity, Bluetooth audio/Bluetooth LE capabilities, and a feature-rich STM32 microcontroller from STMicroelectronics. MAVID also provides multi-protocol connectivity with 2.4/5Ghz dual-band 802.11ac WiFi, Bluetooth 4.1 with audio, Bluetooth LE, concurrent Wi-Fi/Bluetooth operation and protocol support along with RF/antenna coexistence. It also features 1/2/3 mic far-field voice options with full acoustic echo cancellation for ASR and voice communications, beam forming, regional Wake Word recognition, ultra-low power Wake-on-Voice, and embedded RAM and Flash memory. 
 

The GBS is a development kit for the MAVID module that allows quick prototyping and development. The board design integrates 2 digital microphones + 1 analog microphone, DAC, amplifier, speaker driver, battery,  Alexa AVS compliant UI/UX components (buttons/LEDs), and additional test/probe points for the UART/I2C/GPIO interfaces. The kit also includes a FreeRTOS SDK with AWS IoT Core connectivity, secure OTA capabilities, various power save mode implementations, and mobile applications for device config/control over BLE and WiFi + mobile app SDKs for iOS and Android.

"Expanding Libre’s unique MAVID platform into broader IoT and AI applications is a strategic activity and a top priority at Libre,” says Jordan Watters, Chief Executive Officer of Libre Wireless Technologies. “We are investing heavily in new tools, SDK’s and a roadmap of devices to enable the most unique and compelling IoT and AI solutions in the industry, and we are very proud to begin this roll out with Amazon and our new AWS IoT Core SDK platform certification.”
