Android 4.1 vs Android 5.0 Performance Comparison

Most of the time people compare the performance of different hardware platforms, but since Wandboard released an Android 5.0 image in the last few days, I wondered what difference two years of software development may make by comparing benchmark results. So I ran both Antutu 5.6.1 and Vellamo 3.1 on Android 4.1.2 Jelly Bean (android-4.1.2-wand-dual-20130411.zip) and the latest Android 5.0 Lollipop firmware for Wandboard Dual (Freescale i.MX6 Dual) development board. Android 4.1.2 Benchmark Results Antutu 5.6.1 Vellamo 3.1 You’ll notice the yellow triangle on the top right corner of the multicore and browser results due to some warning related to missing CPU frequency information, and a DOM timeout. Android 5.0 Benchmark Results Antutu 5.6.1 The 2D graphics looked weird at some point as it zoomed out on1/4 of the display. The screenshot did not show the total score, so I added it manually to the picture above. Vellamo 3.1 Vellamo […]

Android 5.0 Lollipop Image for Wandboard Development Boards

Wandboard Solo, Dual and Quad are development boards powered by Freescale i.MX6 Solo, Dual, and Quad, that have been launched in 2013. I can remember running Android 4.1.2 and Ubuntu on both Wandboard Dual and Wandboard Quad. Fast forward to 2015, the board is still supported, and Android 5.0 Lollipop beta has been released for the three boards, making these one of the few hardware platforms supporting Android Jelly Bean, KitKat, and Lollipop. You can try it out by downloading the image, and flashing it to a micro SD card (8GB or more) as follows: Linux

Where X is the letter for your micro card which can be found with lsblk command Windows – Download wandboard-lp-5.0.0-20150213-sdcard-boot.img.xz, extract it, and flash to the the micro SD with Win32DiskImager. Insert the micro SD into the micro SD slot on the CPU board, and enjoy! At least in theory… If you have […]

Freetronics Introduces an Arduino Shield for ESP8266 ESP-01 Wi-Fi Module

ESP8622 has drastically brought down the price of adding Wi-Fi to MCU boards such as Arduino UNO,  but you need to add some cables, and take care of 3.3V to 5V conversion for the UART pins either with a divider made of 2 resistors, or a FET level shifter, and you may not be able to access all I/O of ESP8622 on the popular ESP-01 version of the module. For a neater solution, Freetronics had designed ESP-01 WiFi Module Shield that takes care of all these small issues. Key features of the shield: 3.3V regulator dedicated to the module Logic level shifters on TX/RX lines: compatible with both 3.3V and 5V Arduino models Selectable TX/RX pins: use D0/D1 for hardware serial, or D2 – D7 for software serial CH_PD pin on ESP-01 module pre-biased for correct operation mode Extra ESP-01 pins broken out for your own connections Prototyping area with […]

ZRRO Android Game Console Includes a Hover and Touch Controller (Crowdfunding)

Android games are fun to play… on smartphones and tablets, but if you want to play such games on a TV screen via an Android mini PC, it can become more problematic, as most of the games were designed for touchscreen, so you have to be prepare to juggle between input devices.. In my reviews, I have to play Candy Crush Saga with an air mouse, and I switch to a wireless gamepad for racing games such as Riptide GP2 or Beach Buggy Racing, while some games are simply not playable at all without touch emulation, unless you install a software remote such as Droidmote on your smartphone, and use the latter as a controller, which may not be ideal either. ZRRO, an Israeli company, came with a new package comprised of an Android game console (ZRRO Box), and a game controller (ZRRO Pad) featuring a hover and touch surface […]

Voltera V-One is a Low Cost PCB Printer and Solder Paste Dispenser (Crowdfunding)

The traditional hardware development cycle involve sending PCB Gerber files to a manufacturer, wait a few days (or weeks), get the boards back, find and fix bugs, send a new revision of the gerber files to the manufacturer and so on. This wastes a lot of time, so PCB printers capable of handline single and dual layer PCBs have started to see the light of the day, for example with BotFactory Squink. The latter can also do pick and place, but costs over $3,500. Luckily if you’d like something cheaper, Voltera V-One will do many of the same tasks, for but for only $1,500. Voltera V-One specifications: Minimum Trace Width – 8mil (~0.2mm) Minimum Passive Size – 0603 (0402 for solder paste) Minimum Pin-to-Pin Pitch – 0.8mm (0.5mm for solder paste) Resistance – >12 mOhm/sq @ 70um height Max Heated Bed Temperature – 250C Heated Bed Ramp Rate – ~2C/s […]

Power Consumption of Amlogic S812 and Rockchip RK3288 TV Boxes

The recent post comparing the power consumption of ODROID-C1 vs Raspberry Pi boards, as made me want to give another try at power consumption measurements. Regular reader already know I made a power measurement board and cables capable of hading different connectors (micro USB, mini USB, power barrels,  etc..), but eventually it failed to deliver enough current to the boards for any meaning testing. But since I now have a better power supply, and multi-meter, it was worth another try, especially since I could draw some pretty charts. I decided to test the three most popular Chinese SoCs for mini PCs namely Amlogic S812 (4x Cortex A9), Rockchip RK3288 (4x Cortex A17), and Allwinner A80 (4x Cortex A15 + 4x Cortex A7) using respectively Eny M8S, Open Hour Chameleon, and A80 OptimusBoard. If you are paying attention, you must have noticed Allwinner A80 is not part of the title, that […]
