DietPi is Lightweight, Easy to Use Debian Based Distribution for Raspberry Pi, ODROID, and Orange Pi Boards

Raspberry Pi, Hardkernel ODROID, and Orange Pi are some of the most popular and cost effective development boards on the market today, and one British developer, going under Fourdee nickname, has released a lightweight distribution called DietPi working for all Rasbperry Pi boards, ODROID-C1(+), ODROID-XU3/XU4, and Orange Pi PC, with Orange Pi 2 and Orange Pi Plus support coming soon, as well as a VMWare virtual machine also available for evaluation. The compressed downloads are about 80 to 100MB depending on the target, the image that can be dump with dd or Win32DiskImager requires a 1GB or greater micro SD card as the image itself is about 500MB large, Internet access (Ethernet or Wifi), and optionally a USB Drive to allow installation on a USB drive for better performance, which of course does not apply if you have an eMMC module with your ODROID board. The image also contains some […]

SimpleLink Battery-less Power Switch Leverages RF & Energy Harvesting Technologies

SimpleLink may be the name used by Texas Instruments for their wireless MCU family, but there’s also a Chinese company called SimpleLink Technology that develops wireless smart home solutions including battery-less power switches that communicate over sub GHz band to receivers using energy harvested from pressing the button(s) on the switch. They have different models with 1 to 4 buttons, and round and square shapes. Let’s have a look at SIM1010-K1 specifications: Switch Type – Push-Button; operating force: 7N; typical total travel: 4mm Number of Keys – 1 gang Power Mode: Self-Powered Control Distance – Up to 30 meters indoor (works though walls), 100+ meters outdoor Frequency Bands – 433/315/868/915MHz Lifetime – >200,000 times Connectivity – SimpleLink (most probably entirely unrelated to TI SimpleLink); +10dBm Tx power Operating Temperature: -25~70℃ Operating Humidity: 0~95%RH Dimensions – Ф 70 x 15.5 mm Weight – 44g That self-powered wireless switch will prevent the […]

TI SimpleLink CC1310 Wireless MCU Promises 20 Km Range, 20-Year Battery Life on a Coin Cell

Some LPWAN standards such as SigFox, LoRa, or nWave allows for transmission of data at low bitrate over several kilometers, and I’ve very recently featured Microchip’s LoRa modules and motes in this blog. So when Texas Instruments sent their December 2015 newsletter entitled Wireless MCU spans 20 km on a coin cell, I decided to have a look, and the company’s CC1310 wireless Cortex-M3+M0 MCU based on a proprietary sub GHz technology also claims to last 20-year on a coin cell for applications such as grid communication infrastructure and heat and water meters. SimpleLink CC1310 key features: Microcontroller – ARM Cortex-M3 @ up to 48 MHz with up to 128KB programmable flash, 8KB DRAM for cache/general purpose, 20KB Ultralow Leakage SRAM Sensor Controller – Ultralow power and autonomous; 16-Bit Architecture; 2KB of Ultralow Leakage SRAM for code and data RF core Cortex M0 core with 4KB RAM, and ROM Data […]

How to Upgrade SMA-Q Smartwatch Firmware

I’ve started testing SMA-Q smartwatch, and so far I’ve had lots of issues with Bluetooth connectivity. The watch can rarely pair with my Android smartphone, and I was unable to enable features like Anti-lost and Sedendary alerts as the app would always report there was no connection. The company has sent me instructions to upgrade the firmware, and it seems to have improved things a little. So first you need to install SMA Services app by scanning the QR code on the user’s manual, or download the apk by following this link. Once this is done you can register, or skip registration. Now go to Setting, and select Connect watch. You should see a circle as on the left side above reading Searching watch, then Bluetooth Connecting, before seeing a message the connection was successful. You’ll probably them want to tap on Upgrade app, before tapping on Firmware upgrade (local […]

Amlogic S905X and S912 Processors To Support 4K VP9, HDMI 2.0a, Built-in DAC and More

I had heard some news that Amlogic S912 was delayed, and even possibly canceled, while talks about a new S908 processor surfaced recently with support for VP9 up to 4K resolution. We now have some more details as I’ve received some more information about Amlogic product roadmap, and S908 should be renamed S905M [Update: The name will apparently be changed to S905X now, the saga continues…] Amlogic S905 Amlogic S908 / S905M / S905X Amlogic S912 CPU Quad core Cortex A53 @ up to 2.0 GHz Quad core Cortex A53 @ up to 1.5/2.0 GHz Octa core Cortex A53 @ up to 2.0 GHz GPU Penta-core Mali-450 up to 750 MHz High perf gaming GPU Memory 16/32-bit DDR3, LPDDR2/3 Up to 2GB, DDR2133 16/32-bit DDR3/4, LPDDR2/3 Up to 2GB, DDR2400 Storage NAND Flash@BCH60 eMMC 5.0, SD, Nor Flash Video Decoding 4Kp60 10-bit HEVC, 4Kp30 H.264 4Kp60 10-bit HEVC, VP9 4Kp30 […]

Intrinsyc Introduces Qualcomm Snapdragon 820 Cortex-A72-Class Development Board, SoM and MDPs

While there’s already an healthy choice of ARMv8 development board such as LeMaker Hikey, or Qualcomm DragonBoard 410c, all those platforms are based on the lower end Cortex A53 64-bit ARM core, and ARM Cortex A57, let alone Cortex A72, boards are much more difficult to find, as they are much pricier and/or have limited availability. Intrinsyc may have released the first (somewhat) affordable and accessible Cortex-A72-class development board with Open-Q 820 development kit comprised of a SoM and a baseboard, as well as smartphone and tablet mobile development platforms (MDPs) based on Qualcomm Snapdragon 820 quad core Kryo processor. While Kryo is a custom ARMv8 designed by Qualcomm, and not exactly a Cortex A72 core, both have similar performance, as shown in Snapdragon 820 Antutu and Kirin 950 Antutu results. Open-Q 820 board specifications: SoC – Qualcomm Snapdragon 820 quad core Kryo cores with 2x cores @ up to […]

Why Do UL and CE Certifications Matter For Anything That Connects to the Mains (110V/220V) ?

I’ve been featuring a few cheap automation appliances such as Orvibo Wiwo S20 WiFi smart socket or lately Sonoff & Slampher WiFi and RF switch and lightbulb adapter, and people mentioned that Wiwo S20 socket was unlikely to be compliant with CE up to 10A since it lacked the ground pin, and I was also informed that Sonoff & Slampher was probably not compliant with UL certifications. Why does not matter? The picture below may give a clue… UL and CE certifications are used to make sure the device complies with safety regulations, and in some case make also improve reliability, as in UL compliant power supplies will feature inexpensive TVS device to protect against thunder. And if you think you are covered because you have an house insurance, it’s quite likely it will be void if the on-site expert find a non-compliant device on the site of the fire. […]
