Windows 10 on Arm Limitations

Windows 10 on Arm was first demonstrated at Computex 2017 on a reference platform based on Qualcomm Snapdragon 835 processor, at the time, I thought the expected 2-in-1 hybrid laptops based on the solution may bring cheaper Window 10 devices that work just like their x86 competitors, and offers longer battery life. Several models including HP Envy x2 (2017) and ASUS NovaGo TP370 were then announced at the end of 2017, and prices were quite higher than most expected with pricing for the ASUS model starting at $600 with 4GB RAM and 64GB storage. But to be fair, Snapdragon 835 are used in premium LTE smartphones like Xiaomi Mi 6 that sell for around $400 and up. At least, we are still promised good battery life of over 20 hours of continuous use (e.g. playing a Full HD video). When the laptop were announced, I read several blogs and news […]

VideoStrong Introduces Low Cost Version of KI Plus T2 S2 Hybrid Android TV Box with Amlogic S805X Processor

VideoStrong K1 Plus T2/S2 is an Android 5.1 set-top-box with DVB-S/S2 and DVB-T/T2 tuner that was launched roughly two years ago with Amlogic S905 quad core processor. Since then, the company has now launched variant of the model with Amlogic S912 (e.g. KIII Pro hybrid TV box) or Amlogic S905D (e.g. KI Pro set-top box) processors. But now, provided the information on Alibaba is correct, the company has launched a new version of KI Plus T2/S2 with Amlogic S805X which should be cheaper, run a more recent Android 7.1 operating system, at the cost of losing support for 4K decoding, since the processor only support Full HD (1080p60) decoding at most. Since the company updated an existing product, some specific details are wrong on Alibaba, but KI Plus T2 S2 (2018) specifications should be as follows: SoC – Amlogic S805X quad core ARM Cortex-A53 @ up to 1.2 GHz with […]

A First Look at ESP32-LyraTD-MSC Audio Mic HDK with Baidu DuerOS Assistant

Earlier this year, Espressif Systems had unveiled their ESP32-LyraTD-MSC Audio MiC HDK (Hardware Development Kit) which features an ESP32-WROOM module, a 4-mic array DSP, 3 microphones, an audio jack, and various I/Os. I received the board a couple of weeks ago, and while there’s no public information released yet, the company provided me with ESP32-LyraTD-MSC User Guide in English. Eventually, I’d expect Google Assistant and Amazon Alexa to be supported, but in the meantime I had to leverage my (lowly) Chinese language skills to get started since the kit is pre-loaded with firmware connecting to Baidu DuerOS voice assistant. ESP32-LyraTD-MSC Unboxing The kit came in a bland Espressif Systems carton box. Inside the package, I could only find one kit comprised of two boards. The bottom board read ESP32_MicrosemiDSP_Mainboard-V1, and does not show much apart from marking for connectors, headers and the power switch. While the top comes with eight […]

STMicro Introduces Two STM32 Discovery Kits with 2G/3G or 4G LTE-IoT Cat M1/NB1 Connectivity

Embedded World 2018 trade fair will take place on on take place on February 27 – March 1 in Nuremberg, Germany, and we’re starting to see some company announce new products and solutions for the embedded market. STMicro has just announced their showcase their very first cellular development kits at the event, based on a display-less variant on their 32L496GDISCOVERY Discovery board with cellular add-on boards: P-L496G-CELL01 Discovery kit with with a 2G/3G modem P-L496G-CELL02 Discovery kit with with an LTE-IoT Cat M1 (eMTC) / NB1 (NB-IoT) / 2G model Now the company has not started designed their own cellular modem, but instead relying on QUECTEL modems. Both kits share most of the same specifications: MCU – STMicro STM32L496AGI6 Arm Cortex M4F MCU@ 80 MHz with 1 MB Flash, 320 KB RAM in a UFBGA169 package On-board memory – 8 Mbit PSRAM On-board + external storage – 32 KB I2 […]

WCH CH341 USB to Serial Chip Gets Linux Drivers to Control GPIOs over USB

USB to serial chips are often used as a debug interface either directly on the target board, or via a dedicated debug board. But some models have extra pins exposed, and one of those is WCH CH341, which also includes I2C & SPI interfaces and up to 8 GPIOs. But software support for those extra pins is not currently built-in into the drivers found in Linux mainline, and you’d also have to find a board that breakout the relevant pins. It turns out there are few of things including “CH341A ALL IN 1 USB to SPI/I2C/IIC/UART/TTL/ISP serial adapter” board going for $10 shipped on Aliexpress, and which Zoobab successfully used to control 6 (out of 8) GPIOs over USB. The board comes with a USB board to connect to your computer, several header for I2C, UART, SPI, some LEDs, and jumper to select I2C/SPI or UART mode and voltage (5V/3.3V). […]

CYCPLUS A2 is a 3-in-1 Device Combining Power Bank, Air Pump and Flash Light

Sometimes I come across some products that do not seem to make any sense. I had that exact feeling when I first discovered CYCPLUS A2, an air pump with a battery, and a flash light to top it out. But as I read more about it, this 3-in-1 gadget may indeed be useful to cyclist, since it offers a convenient way to inflate tires, provides backup power for your smartphone, as well as a backup light in case the one on your bike gets broken for instance. CYCPLUS A2 specifications: Display to set pressure and check status Buttons to adjust settings and turn on/off light Maximum Pressure – 150 PSI / 10.3 BAR / 990 KPA / 10.5 kgf/cm2 Inflation Time – Car: 8 minutes; road bike: 2.5 minutes; mountain bike: 2 minutes; basketball: 30 seconds Light – 80 lumen USB – 1x micro USB port for charging, USB type […]

Wibeee Power Monitoring Device Plugs right into Your Home’s Circuit Breaker Box

We’ve covered several smart plugs or switches capable of monitoring electricity consumption and displaying results right in a smarphone app, or computer’s web browser with products such as Sonoff S31 or Broadlink SP2 WiFi smart sockets, or Sonoff POW switch. Those work for individual plugs, but if you want to cover your full house, you’d need several of those, and in some case it may not be so convenient as no plugs may be available for example for lights or air conditioner. Smilics Technologies has come up with an easier method, although less granular, thanks to their WIBEEE device that clips to your fuse / circuit breaker box using DINZERO “clip-on” technology, and available in single and three phase models. Main features: Voltage Range – 85 to 265 V AC @ 50 ~ 60 Hz with 2% accuracy + variation in range of use depending on temperature, humidity, etc… Current […]

Onda V18 Pro (Allwinner A63) 2K Tablet Review – Part 1: Unboxing, First Boot, and Antutu 7 Benchmark

Announced last June, Allwinner A63 is the latest tablet SoC from the company, with a quad core Cortex A53 processor and a Mali-T760MP2 GPU capable of driving 2K displays. One of the first tablet to feature the SoC is Onda V18 Pro with a 10.1″ 2560×1600 high resolution display, 3GB RAM, 32 or 64GB internal storage, and the capability to play 4K H.265/H.264/VP9 videos (obviously downscale to the display resolution). I was interested in checking it out, and GearBest sent me a sample of the 32GB flash version. I’ll do a two part review, starting with unboxing, and first boot where I’ll run CPU-Z and Antutu, before publishing the rest of the review in a few weeks once I got to use it more and performed more tests. Onda V18 Pro Unboxing The tablet comes is a white “V-series” box, Onda likely uses for all their VXX tablets.They just differentiate […]
