$23 Sonoff 4CH Pro 4-Channels WiFi & RF Switch Ships in a DIN Rail Enclosure

ITEAD Studio’s Sonoff family is a collection of really useful and inexpensive home automation devices which have been featured multiple times on CNX Software with either to stock firmware and eWelink app, or open source firmware developed by the community. I’m using a Sonoff TH16 to control a water pump, a Sonoff Pow to monitor my office’s power consumption, and Karl used some Sonoff switches to control his lights at home. The company has now launched Sonoff 4CH Pro with 4 relays that can be controlled with buttons on the unit, WiFi, or RF remote controls, and comes in a DIN Rail enclosure. Sonoff 4CH Pro switch specifications: Connectivity – ESP8266 WiFi module and 433 MHz receiver Relays – 4x HUIKE 230V/10A relays (max 2200W per relays) with NC and NO connection Configuration – K5 & S6 switch for mode selection; K6 switch for time selection (0.5 to 4s) Misc […]

$10 Smartphone Display Released for Orange Pi 2G-IoT Board

Orange Pi 2G-IoT is a low cost ARM Linux board with 2G, and WiFi & Bluetooth connectivity, basically with the guts of a smartphone minus the display and battery. Shenzhen Xunlong has now released a 800×480 display with capacitive touch support for the board available in black or white, and selling for $9.98 plus shipping. The board is too thick to make a smartphone out of it, but it reminds of the very expensive Qualcomm MDP’s (Mobile Development Platform), so Android app developers may find some use to test their apps on lower end hardware. It could also be used for control panels that do not need to be very thin. Orange Pi 2G-IoT display specifications: 3.5″ TFT Display with 800×480 resolution Capacitive touchscreen Case with the Back, Home, and Recent buttons Dimensions – With case: 57.14 x 96.85 x 2.0 mm; Display only: 51.84 x 86.4mm Software support is […]

Micro SD Cards for Development Boards – Classes, Tools, Benchmarks, Reliability, and Tips & Tricks

When people plan to use a development board for their project, they mainly focus on the requirements of the development board itself, as well as software support. But selecting the right accessories may be just as crucial for good performance and stability. For example, selecting a proper power supply is important, as the board may freeze or randmly rebooted if it is not feed at the right voltage. Part of this is selecting a micro USB cable, as you’ll want a cable with minimal resistance which can be achieved through shorter cables and/or a low AWG value. Another important item that can impact stability and performance of the systems are micro SD cards when used to run the operating system in development boards. Understanding SD Card Performance Metrics & Classes Until a few years ago, (Micro) SD cards were primary used to store data such as photos, videos and music. […]

OpenDime is a Bitcoin USB Stick based on Microchip SAMD21 MCU, and ATECC508A Security Chip

The first time I heard about crypto currencies, specifically Bitcoin, was probably around 2011, and later in May 2012, I noticed a “micro-payments with Bitcoin digital currency” talk at a Barcamp. I did not think much of it at the time, but with hindsights, I should definitely have started to mine some Bitcoins considering the price was $5. Nevertheless, cryptocurrencies appear to be here to stay, and while most transactions occurs over the Internet, Opendime project has made a hardware USB dongle to store Bitcoins, and earlier this year, announced version 2 of their “Verified Bitcoin Credit Stick”. Hardware specifications of OpenDime v2.0 / v2.1 USB stick: MCU – Microchip / Atmel SAMD21 Cortex M0 MCU Security Chip – Microchip / Atmel ATECC508A Crypto chip with support for SHA-256, TRNG, and public key signing (ECDSA) USB 2.0 interface to connect to a computer Bitcoin seal The USB stick works like […]

Android Can Now Boot with a Full Open Source Graphics Stack on NXP i.MX6 Boards

While the Android operating systems is itself open source, it still relies on proprietary binary files to leverage GPU acceleration, VPU hardware decoding, wireless connectivity, and so on. It’s been possible to run Android with an open source software graphics stack, but it’s normally terribly slow and barely usable. But Collabora has announced it could now boot Android with a full-graphics stack on iMX6 platforms using no proprietary blobs at all. To do so, they leveraged the work done on Etnaviv open source drivers for Vivante GPUs, and adding the different formats used for graphical buffers in Android and Mesa library using modifiers representing different properties of buffers. They further explain: Support was added in two places; Mesa and gbm_gralloc. Mesa has had support added to many of the buffer allocation functions and to GBM (which is the API provided by Mesa, that gbm_gralloc uses). gbm_gralloc in turn had support […]

HiMedia Q30 (Hisilicon Hi3798MV200) Android TV Box Review – Part 1: Unboxing and Teardown

I’ve often read praises about HiMedia TV boxes in the comments section of this blog, but so far, I had never tested any of their products. This is about to change, since the company has sent me their latest HiMedia Q30 TV box running Android 7.0 on Hisilicon Hi3798MV200 processor, a cost-down version of Hi3798CV200 processor with the same CPU,a lower-end Mali-T450 GPU, about the same media capabilities, and less I/Os. I’ll start the review by checking out the TV box and accessories, as well as the PCBA, before reporting the experience with Android 7.0 firmware in several weeks. HiMedia Q30 TV Box Unboxing I received the device is a package that read “HIMEDIA Q30” and “Android TV Box”, and shows some of the key features like 4K @ 60 fps, 10-bit HEVC, HDR and Kodi support. The devices ships with an IR remote control with IR learning function for […]
