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.

Unboxing and Teardown of Eny EM95 4K Android TV Box with Front Panel LCD Display

Eny EM95 was first unveiled in early July, as the flow of Android TV boxes based on Amlogic S905 started. Eny Technology has now sent me a sample of this device with the typical 1GB RAM and 8GB Flash, but it adds an LCD display on the front panel.

LoRa is one of those long range low power WAN standards used for the machine to machine (M2M) and Internet of things (IoT) applications. I already featured a Semtech Lora module here with a line-of-sight range of up to 20 to 30km, and the company has just partnered with STMicro to deploy LoRa solutions, but today, I’m going to have a look at Microchip Lora modules and development kits that I discovered in the company’s Micro Solutions Nov/Dec 2015 publication. The company has launched two modules for the European and North American markets with respectively RN2483 LoRa 433/868 MHz R&TTE Directive Assessed Radio Modem and RN2903 915 MHz North American modem.

Review of MINIX NEO U1 Media Hub

We’ve already seen that MINIX NEO U1 has some impressive hardware to offer with a good thermal solution, and high-end chips for storage and WiFi, as well as some neats additions like RTC support. But obviously the most important is to find out how the box performs, so I’ve put it through it spaces with video playback and features testing, as well as some benchmarks. First Boot, OTA Firmware, Settings and First Impressions The device has three full-sized USB 2.0 ports, which become four once we had the provided USB OTG adapter to the remaining micro USB port.

After inserting HDMI, optical audio […]

The company has now uploaded the Android 5.1 SDK, including Linux 3.10.79 kernel, on github. It’s not for the Android SDK for RK3368, but at least it’s not just an outdated tarball, and will hopefully be regularly updated directly on github. Beside the source code, the company also released three firmware image including Rockchip’s Light Biz OS desktop operating system based on Lollipop: Biz OS for GeekBox – V151208 (8th of December 2015) Android and Lubuntu dual boot image  – V151129 (29th of November 2015) Android 5.1 image – V151129 (29th of November 2015) It’s quite possible those images will also work on other Rockchip RK3368 platform with some modifications, e.g. an updated device tree file for a given hardware.

Allwinner A64 Android 5.1 SDK and Linux Source Code

Allwinner A64 is likely to become quite popular as it will be used in PINE A64 board, Olimex open source hardware laptop featuring A64-OLinuXino board, and some low cost tablets. We’ve already got some documentation such as Allwinner A64 datasheet and user’s manual, but AFAIK, there was no source code released for the board. The good news is that you can now download Android 5.1 SDK and Linux source code on Baidu with four files available: lichee_A64_A5.1_V1.0.tar.gz – Linux source code android_A64_A5.1_V1.0.tar.gz– Android 5.1 SDK android_prebuilts_A64_A5.1_V1.0.tar.gz – Some pre-built binaries for Android A64硬件资料.zip – Documentation including the datasheet, product brief, and user’s manual which we’ve already got, but also some hardware with reference schematics, PCB layout files, and BoM for an Allwinner A64 tablet. That’s about 7.4GB to download, and apart from the documentation, the download is not quite complete yet, so I could not look into the details of […]
