$129 Allwinner R18 based 3-Mic Far Field Amazon AVS Development Kit in the Works

Allwinner-SoC-Only-3-Mic-Far-Field-Dev-Kit-for-Amazon-AVS

Several companies are already offering development kits for Amazon AVS (Alexa Voice Service), but as we’ve seen in the past, those are rather expensive with far-field kits such starting at $349 with kits such as Synaptics AudioSmart 4-Mic Development Kit, or Intel Speech Enabling Developer Kit, and hands-free kits being barely cheaper at $299 and up. But there will soon be a cheaper solution, as Allwinner and SinoVoIP (aka Banana Pi) are working on “SoC-Only 3-Mic Far-Field Dev Kit for Amazon AVS” that includes 3 microphones, and works without special DSP, relying instead on Allwinner R18 processor’s audio codec and capabilities. Allwinner SoC-Only 3-Mic Far-Field Dev Kit for Amazon AVS (aka R18-AVS-EVK) specifications: SoC – Allwinner R18 quad-core Cortex-A53 processor @ 1.15GHz with Mali400MP2 GPU System Memory – 1GB DDR3 Storage – 8GB eMMC flash Video Output – HDMI Audio – 6x Microphones, 2x AEC, AUX and headphone output; GMEMS voice […]

Amazon FreeRTOS Released for NXP, Texas Instruments, STMicro, and (soon) Microchip Microcontrollers

FreeRTOS is an open source real-time operating system for microcontrollers released under an MIT license, and when it comes to adoption in embedded systems it’s right there near the top with embedded Linux according to Aspencore 2017 embedded markets study. For example, some Espressif SDKs for ESP8266 or ESP32 are based on FreeRTOS, and so is Mediatek LinkIt Development Platform for RTOS. The recently announced Amazon FreeRTOS (a:FreeRTOS) leverages the open source operating systems, and extends it with with libraries that enable local and AWS cloud connectivity, security, and soon over-the-air updates. a:FreeRTOS is free of charge, open source, and available today. In order to get started, you’ll have a choice of 4 hardware platforms: STMicro STM32L4 Discovery Kit IoT Node (B-L475E-IOT01A) powered by STM32L475 ARM Cortex-M4 MCU with 802.11 b/g/n WiFi, Bluetooth 4.1 LE, RF (868 / 915 MHz), and NFC connectivity, plenty of sensors NXP LPC54018 IoT module (OM40007) […]

Amazon Fire TV Stick Basic Edition Ships to over 100 Countries for $50

Amazon products are usually launched in the US, and a limited number of European countries, meaning most people can’t purchase or use their devices without going through various hoops. But the company has now launched a basic edition of their latest Fire TV stick 2016 sold in over 100 countries. Basic means it supports Amazon Alexa voice services, and you pay around $10 extra for the privilege. Apart from that it looks exactly the same. Supported languages are still quite limited with Spanish, Brazilian Portuguese, French, Italian, German, or English, and the company mentions people will have access to videos from Amazon Prime Video with “unlimited access to critically acclaimed shows like The Tick, American Gods, and The Man in the High Castle as well as The Grand Tour Season 2″ Hardware looks the same with a quad-core processor coupled with 1 GB of memory and 8 GB of storage […]

Intel Speech Enabling Developer Kit Works with Alexa Voice Service, Raspberry Pi 3 Board

We’ve known Intel has been working on Quark S1000 “Sue Creek” processor for voice recognition for several months. S1000 SoC is based on two Tensilica LX6 with HiFi3 DSP, some speech recognition accelerators, and up to 8x microphones interfaces which allows it to perform speech recognition locally. The solution can also be hooked to an application processor via SPI, I2S and USB (optional) when cloud based voice recognition is needed. Intel has recently introduced their Speech Enabling Developer Kit working with Amazon Alexa Voice Service (AVS) featuring a “dual DSP with inference engine” – which must be Quark S1000 – and an 8-mic array. The kit also includes a 40-pin cable to connect to the Raspberry Pi 3 board. Intel only provided basic specifications for the kit: Intel’s dual DSP with inference engine Intel 8-mic circular array High-performance algorithms for acoustic echo cancellation, noise reduction, beamforming and custom wake word […]

Dragonwally is a Stereoscopic Computer Vision Mezzanine for 96Boards CE Boards

Hardware based on 96Boards specifications may not have the number of sales as Raspberry Pi or Orange Pi boards, but there’s heavily used by Linaro member and other developer working on bleeding edge software. More and more companies are designing boards compliant with the standard, and several new mezzanine expansion boards such as Secure96, were showcased at Linaro Connect SFO 2017, and are yet to be show up on 96Boards Mezzanine page. Another 96Boards mezzanine expansion board in development is Dragonwally, designed for stereoscopic computer vision, currently used with DragonBoard 410c board, and targetting applications such as object recognition,  people counting, access control, or driver identification and safety. DragonWally DW0 board specifications: MIPI DSI interface with high speed connector 2x 5MP cameras 1x USB port 96Boards CE compliant The two Brazilian developers working on the project interfaced it with DragonBoard 410c running Linaro Debian, and using OpenCV and Python for […]

NComputing RX300 Thin Client Review – Part 2: Hardware Setup, Windows Server 2016

Ncomputing RX300 is a thin client based on Raspberry Pi 3 board, allowing to run Windows operating systems on a powerful server with the Raspberry Pi 3 handling the display, audio, and keyboard/mouse inputs. The company sent me a sample for review, and I checked out the hardware and accessories in the first part entitled “NComputing RX300 Thin Client Review – Part 1: Unboxing and Teardown“, so in the post I’ve started the thin client, and connected it to vSpace Pro server. Hardware Setup RX300 uses the same peripherals as any mini PC, so I connected USB keyboard and mouse, an Ethernet cable (WiFi is also possible), and the power adapter. You could also connect other devices, and I added a USB flash drive which, as we’ll see later, will be properly recognized by the server. I was also sent a USB to VGA adapter that you can connect to […]
