Meet NXP i.MX8 Processor Families: i.MX 8 for High performance, i.MX 8M for Audio/Video & i.MX 8X for Low Power

Freescale and then NXP have been talking about i.MX8 processors for several years, and this spring unveiled i.MX 8 Multisensory Enablement Kit without giving much details about the processor except it would include both Cortex A72 & A53 cores. But NXP put out a press release yesterday about “Multisensory Automotive eCockpit Platform to Advance Multimedia Experiences in Future Cars” which appears to be the same news but with different words, except the content of the PR has more interesting bits such as: The new family, which is based on up to six 64-bit ARMv8-A technology processor cores and includes a HiFi 4 DSP, LPDDR4 and DDR4 memory support as well as dual Gigabit Ethernet with audio video bridging (AVB) capability, is designed to advance automotive dashboard graphics such as instrument clusters, infotainment visuals, heads-up displays, rear-seat screens and more. Capable of driving four HD screens with independent content or a […]

Two More Google Products: Google WiFi Mesh Router, and Google Home, an Amazon Echo Competitor

Google made a bunch a new product announcements with their Pixel phones, Daydream View VR headset, and Chromecast Ultra 4K dongle, but in this post I’ll write about two other new products: Google Home an Amazon Echo competitor powered by Google Assistant and supporting multi-room, as well as Google WiFi (Mesh) router aiming at providing WiFi all over the house by combining multiple WiFi routers. Google WiFi Router Most households now use a single router to provide WiFi to the home, but inevitably this introduce some dead or “slow WiFi” zones within the house. One way to work around this is to use WiFi repeaters, but it’s not always easy to setup and may lead to lower bandwidth. Google WiFi router uses a technology called mesh WiFi, where each router work together to determine the best path for your data using Network Assist technology to automatically choose and update the […]

Review of Allo Vana Player Linux HiFi Audio System with Max2Play, SqueezeBox and Kodi

Last month I showcased what I called “Allo Sparky Audio Kit” with a DAC board (Piano), an amplifier board (Volt), and usually hard to find reclocker and capacitance multiplier boards (Kali & CM), all connected to Allo Sparky ARM Linux development board powered by Actions Semi S500 quad core Cortex A9 processor, and running Ubuntu 12.04. In the first post, I just described the boards, and showed how to assemble the kit, but now that I have received the user’s manual, it turns out the kit is actually called “Vana Player” and the provided Ubuntu firmware image runs Max2Play Browser based system that’s also available for Raspberry Pi and ODROID boards. Before starting the kit, you’ll need to connect speakers to Piano DAC board and/or Kali board, as well as a 19.5V power source such as a laptop power supply to connect to the CM board. I connected some USB […]

$16 and Up RGB LED Bluetooth 4.0 Light Bulbs include Speakers

I’ve just stumbled upon “H1007 Smart E27 Bulb Bluetooth 4.0 Speaker” on GeekBuying. It’s a smart Bluetooth 4.0 RGB LED E27 light bulb that also include a speaker, and sells for $22.59 shipped. I find it’s a good idea, and after looking for other models, I’ve found the $99 Twist light, as well as a much cheaper “OY-QP-BM13” model on eBay going for $15.99. I’ll look at (HZ-)H1007 specifications first: Light Bulb 5W; adjustable RGBW; 330 Lumens; Color temp: 6500K Screw Type – E27/E26 Connectivity – Bluetooth 4.0 LE up to 20 meters range Audio – 3W amplifier; 3D surround audio Voltage – 100 to 240V 50/60Hz Dimensions – 72 mm diameter x 136 mm length Weight – 146 grams The body of the light bulb is available in white, red, golden, and blue, and it ships with a user’s manual in English and Chinese. I could not find the […]

Widora-NEO OpenWrt WiFi IoT & Audio Board is Based on Mediatek MT7688 SoC, WM8960 Audio DAC

A couple of weeks ago, I reviewed ReSpeaker board combining MediaTek MT7688 WiFi SoC with WM8960 audio DAC, running OpenWrt, and allowing you to perform tasks using text-to-speech and speech-to-text thanks to the built-in microphone (or optional microphone array), and a 3.5mm audio jack to connect speakers, as well as several I/O pins. It turns out there’s been board with similar features, minus the built-in microphone, available in China for a while. Meet Widora-NEO. Widora-NEO board specifications: SoC – Mediatek MT7688AN MIPS SoC @ 580 MHz with built-in WiFi System Memory – 128 MB RAM Storage – 16MB SPI flash, micro SD card Connectivity – 10/100M Ethernet, 802.11 b/g/n WiFi 1T1R up to 150 Mbps with PCB antenna, or IPEX connector Audio – 3.5mm jack for stereo headphone and mono microphone, WM8960G audio codec USB – 1x micro USB port for programming via CP2104 chip, 1x micro USB host (or […]

Allo Sparky Audio Kit Combines an ARM Linux Board with Amplifier, Audio DAC, Reclocker and Capacitance Multiplier Boards

Last year I wrote about Allo Sparky SBC Linux and Android development powered by Actions Semi S500 quad core Cortex A9 processor, which mostly differentiates itself from the competition by the many add-on boards for audio, VoIP, and IoT (WiFi+Bluetooth+Zigbee ). While most of development boards are manufactured in China, Allo company is based in India, and all boards are manufactured there, which could be a benefit to Indian readers who want to avoid potential custom issues with other boards. The company has shipped me their complete audio development kit, and I’ll first check out the hardware, before taking time to experiment with the kit in a few weeks or months… I could find 6 different boards in the kit, which I detailed below, as well as a 5V/3A power supply with AU and EU adapter, a micro USB adapter, a micro SD card apparently pre-loaded with Ubuntu 12.04, a […]

Getting Started with ReSpeaker WiFi IoT Board’s Audio Capabilities, Voice Recognition and Synthesis

ReSpeaker is a development board combining an Atmel AVR MCU, a MediaTek MT7688 WiFi module running OpenWrt, a built-in microphone, an audio jack, and I/O headers to allow for voice control and output for IoT applications. That means you could make your own Amazon Echo like device with the board and add-ons, use it as a voice controlled home automation gateway and more. The board was launched on Kickstarter a few days ago, and already raised $100,000 from about 100 backers, but I’ve received an early sample, so I’ll provide some more information about the firmware, and shows how to use with some Python scripts leveraging Microsoft Bing Speech API. You’ll need a micro USB to USB cable to connect your to computer (Linux, Windows, Mac OS…), and a speaker to connect to the board. Linux (OpenWrt) boots in a few seconds, and once it’s done all RGB LED will […]
