AllWinner Announces A31s Processor for Phablets, Hints about Ubuntu Devices

AllWinner is currently a Mobile World Congress 2013, and Charbax had the chance to interview Eva, manager at AllWinner, and learn more about new processors, and future plans by the company. They spent some time discussing about AllWinner A31 and AllWinner A20 quad and dual Cortex A7 processors, but since we’ve know about those for a while I’ll skip this part. The most interesting part is about AllWinner A31s, a cost down version of A31, specifically designed for phablets (smartphones with 5″ to 7″ screens). Like AllWinner A31, AllWinner A31s is also a quad core Cortex A7 processor with PowerVR SGX544MP2 GPU (8 shader engines) and the following specifications: CPU – ARM Cortex-A7 Quad-Core with 256KB L1-Cache/1MB L2-Cache GPU – POWERVR SGX 544MP2 with 8 logic cores. OpenGL ES2.0, Open CL1.x and DX 9_3 compliant. Memory 32-bit Dual-Channel LPDDR2/DDR3/DDR3L Controller, 8-bit NAND FLASH Controller with 64-bit ECC Video UHD H.264 […]

$35 expEYES Junior Transforms the Raspberry Pi, Aakash2 Tablet or any Linux Powered Device into an Electronics Lab

I remember in high school in France, our class only had 2 oscilloscopes and few other electronics equipment, needless to say I did not actually get to use an oscilloscope until I went to university. It would have been nice to be able to play around with oscilloscopes, frequency generators, etc… earlier, but due to budget constraints, this was not possible. Dr Ajith Kumar, a scientist working with the Inter University Accelerator Centre of India, has spent several years working on an ultra low cost electronics lab composed of an oscilloscope and a signal generator to provide students attending schools that cannot afford regular equipments. This learning & experimentation tool is called expEYES, and a prototype was demonstrated last year with the Raspberry Pi. At the end of last year, the final version called expEYES Junior (aka expEYES 2.0) was announced, and is now available to schools and hobbyists in […]

$21 CARAPP APP327 Bluetooth OBD2 Car Diagnostic Scanner

As cars become more sophisticated, you’re now able to access all sort of data from your car and display this on a computer or tablet to diagnose problems or simply to create your own high-end dashboard. This morning, I’ve come across CARAPP APP327, a Bluetooth diagnostic scanner compatible with OBD2 standard (On-Board Diagnostic II), which could can just connect on an OBD2 connector if your car is recent enough. This has been around for many years (since 1996), but I had never heard about this technology until today. Wikipedia OBD2 page explains the OBD2 connector (16-pins) should be within 2 feet (0.61 m) of the steering wheel according to the standard, which also specifies the type of diagnostic connector and its pinout, the electrical signaling protocols available, and the messaging format. After you connect the Bluetooth adapter, you just need to install the applications needed for your platform (e.g. Android, […]

Adding Wi-Fi to Emcraft Systems K70 SoM

Emcraft Systems K70 SoM is a system-on-module powered by Freescale K70 Cortex M4 micro-controller with enough RAM (64 MB) to comfortably run uClinux. They used to charge $99 for their uCLinux BSP, but it’s now free of charge, and the company also provides full hardware and software documentation, including a getting started guide, schematics and BoM for the baseboard, application notes and more… Many of their clients want to use Wi-Fi with K70 SoM, and it can easily be done by using Wi-Fi USB dongles based on Ralink RT5370 chipset such as D-Link DWA-140 (H/W rev B3) or Comfast CF-WU815N. Emcraft has provided detailed instructions to do so with K70 SoM, their latest baseboard (SOM-BSB-EXT) and a demo image based on their uClinux BSP. I’ll summarize the instructions to use K70 SoM as a Wi-Fi access point below. Connect the baseboard and K70 SoM with an Ethernet cable, a mini […]

Nvidia Tegra 4 Benchmarks on Tablet Reference Design

Mobile World Congress 2013 has just started. Nvidia is showcasing both a smartphone reference platform based on Nvidia Tegra 4i (Phoenix reference phone) and an unnamed tablet reference design with Tegra 4 during the event, and several Android benchmarks have been run on the platform including Antutu and Quadrant. The results in the quad-core Cortex A15 Tegra 4 are really impressive with over 36,000 in AnTuTu and 16,000 in Quadrant, which are the best scores ever reported (by far) on those two benchmarks, as the top score in Antutu achieved with an overclocked Galaxy Note 2 is just over 27,000, a phone like the HTC One X scores around 5,600… Android Police also ran two other benchmarks that can help to access web browsing performance: Vellamo (HTML5) and SunSpider. The Tegra 4 completes SunSpider in 494ms (vs 1124ms with HTC One and 208ms in my desktop PC), and scores 3300 […]
