Onion Omega is an Atheros AR9331 Wi-Fi Module Supporting Various Docks and Add-on Boards (Crowdfunding)

There are so many inexpensive Wi-Fi modules running Linux that it would be easy to discard Onion Omega as yet another Wi-Fi module based on Atheros AR9331 WiSoC. However, the developers have tried to bring some added value by making programming easier for web developers, integrating it with a cloud platform (free for non-commercial use), and providing basicor Arduino dock, and add-on boards for Ethernet, OLED, Relay… to make building hardware projects easier too. Let’s go through the hardware first, starting with the module specifications: SoC –  Atheros AR9331 400MHZ MIPS 24K System Memory – 64MB DDR2 400MHz Storage – 16MB Flash Connectivity – 10/100 Mbps Ethernet + 802.11b/g/n Wi-Fi up to 150Mbps with PCB antenna w/ uFL connector I/Os –  18 GPIOs USB – 1x USB 2.0 Power Supply – 3.3V; Typ. consumption: 0.6W Dimensions – 28.2mm x 52mm (1.1″ x 2.0″) Since this type of module is not […]

Wi-Fi SD Card Adapter for micro SD Cards Sells for $15 and Up

Wi-Fi SD cards are mostly used with camera in order to wirelessly transfer photos or/and videos to your computer or mobile device without having to take out the card or transfer them via a micro USB cable. I first discovered this type of card with Toshiba FlashAir in 2011, but now EyeFi seems to be the most popular brand, and comes in different sizes with the 8GB Wi-FI SD card selling for $44 on Amazon US. There are cheaper alternatives with some Wi-Fi SD card adapters accepting micro SD card selling for about $15 and up on Aliexpress or Buyincoins, and DX calls it CY EP-027, but sells it for $23. It does not come with storage but since a 8GB class 10 SD card now costs about $8, it’s still nearly 50% cheaper compared to the 8GB EyeFi SD card. Some features of the card: Max micro SD card […]

MXCHIP EMW3162 is a $10 Low Power Wi-Fi Module for IoT Applications

You can’t beat ESP8266 Wi-Fi modules on price to add Wi-Fi to your IoT projects, but Hackaday found a new Wi-Fi module by Shanghai MXCHIP Information Technology that sells for $10 on Seeed Studio or Amazon US, that should be better suited to battery operated project thanks to a lower power consumption. EMW3162 also features a more powerful STM32F205 cortex M3 micro-controller, as well as more I/Os than ESP8266. Specifications for EMW3162 Wi-Fi module: MCU – STM32F2 Cortex M3 MCU @ 120 MHz with 128KB RAM, 1MB flashOn Wi-Fi connectivity 802.11b, 802.11g, 802.11n (single stream) on channel 1-14 @ 2.4GHz WEP, WPA/WPA2 PSK/Enterprise (hardware encryption) Transmit power: 18.5dBm@11b; 15.5dBm@11g; 14.5dBm@11n MIN Receiver Sensitivity: -96 dBm Max Data rate: 11Mbps@11b; 54Mbps@11g; 72Mbps@11n HT20 Wi-Fi modes: Station, Soft AP and Wi-Fi direct Advanced 1×1 802.11n features: Full/Half Guard Interval, Frame Aggregation, Space Time Block Coding (STBC), Low Density Parity Check (LDPC) Encoding […]

Cubieboard4 Benchmarks in Android

Last time I tried running benchmarks in an Allwinner A80 board (A80 OptimusBoard), it either rebooted during the benchmark, or had fairly disappointing results for example for USB storage. I documented my findings in a post entitled “Current Performance and Stability Issues on AllWinner A80 OptimusBoard Development Board” which was written in October 2014. But a few months have passed, and since Cubieboard4 is another hardware platform, so I was interested in running benchmarks including storage and networking performance testing on the new board to see if any progress was made. Cubieboard4 Android Benchmarks – Antutu, Vellamo, and 3DMarks Manufacturers can add the key ro.sys.hiritsu to build.prop in order to artificially inflate their Antutu scores with Allwinner A80 processor. So before running Antutu, I checked /system/build.prop in the firmware, and found out no trace of this variable, which can only be good for CubieTech reputation. CC-A80 board, the other name […]

Iocean M6752 Smartphone Review

Last week I provides specs, took some pictures, and run Antutu benchmark on Iocean M6752, a 64-bit ARM smartphone powered by Mediatek MT6752 octa-core Cortex A53 processor with 3GB RAM, 16 GB eMMC, and a 5.5″ FullHD display. I’ve been using the device as my main smartphone for over a week, and I’m now ready to write a full review for the phone. General Impressions At first the material and color used on the back cover feels a little strange, but I quickly got used it, and the build quality seems pretty good, and the phone is very light. I must have made one or two calls during the week, and I mainly use my smartphone to check emails, run social network apps, browse the web, play some casual games like Candy Crush Saga, watch YouTube videos, and make Skype calls, and for these tasks I could not really fault […]

Giveaway Week – SoundMate WM201 Wireless Audio Streamer

All good things must come to an end, and this is the last day of Giveaway Week on CNX Software with Uyesee SoundMate WM201 wireless audio streamer that adds Wi-Fi connectivity to your speakers or old AV receiver, so that you can stream audio via EZMusic or a DLNA app in Android, iOS or, desktop computers. If you’ve ever used an EZCast dongle, the app looks just the same except it’s limited to audio streaming. I’ve tried it with an optical audio cable connected to the S/PDIF input of the device and Onkyo TX-NR636 AV receiver. It worked pretty well, as long as your device is in the same room, but if you move to another room, the connection become unreliable, and audio may cut from time to time. You can read SoundMate WM201 review for details. imply leave a comment below to enter the draw, with other rules as […]
