RabbitMax Flex is an add-on board for the Raspberry Pi boards with 40-pin headers, namely Raspberry Pi Model A+ and B+, Raspberry Pi 2, Raspberry Pi 3 and Raspberry Pi 0, destined to be used for Internet of Things (IoT) and home automation applications thanks to 5x I2C headers, a relay, an LCD interface and more. I’ve received a small kit with RabbitMax Flex boards, a BMP180 temperature & barometric pressure I2C sensor, and a 16×2 LCD display. RabbitMax Flex specifications: Relay – Songle SRD-05VDC-SL-C supporting 125V/250VAC up to 10A, 30VDC up to 10A Storage – EEPROM with some system information for identification IR – IR LED, IR receiver Misc – Buzzer, Button, RGB LED Expansion Header for LCD character display + potentiometer for backlight adjustment 5x 4-pin headers for I2C sensors Dimensions – Raspberry Pi HAT compliant The assembly of the kit is child’s play as you don’t even need […]
Tizen may not be overly used in devices, but there has been ports of the operating system on various ARM platform, mostly development boards, powered by Allwinner, Rockchip, Freescale SoCs, and more… Seeing the popularity of Raspberry Pi 2 Model B, Samsung Open Source Group decided to port Tizen to the latest version of the hobbyist board. The full instructions are rather long, and provided in the link above, but the main steps – using a Linux based computer – can be summarized as follows: Create a local copy of tizen-distro Add Raspberry Pi 2 BSP Meta repository Initialize the environment and modify some config files Start the build with Yocto: bitbake rpi-hwup-image. This should make a minimal headless? image Create an SD card image with tmp-glibc/deploy/images/raspberrypi2/rpi-hwup-image-raspberrypi2.rpi-sdimg using dd, an optional resize the parition with gparted or fdisk/resize2fs. Insert the SD card in to your Raspberry Pi 2, and have […]
FOSDEM (Free and Open Source Software Developers’ European Meeting) takes place every year during the first week-end of February. This year the developer-oriented event expects to bring over 5000 geeks to share ideas and collaborate on open source projects. Contrary to most other events, it’s free to attend, and you don’t even need to register, just show up. FOSDEM 2015 will take place on January 31- February 1 in Brussels. There will be 551 sessions divided into 5 keynotes, 40 lightning talks, 6 certification exams, and with the bulk being developer rooms and main tracks, divided into 7 main tracks this year: Languages, Performance, Time, Typesetting, Hardware, Security and Miscellaneous. I’m not going to attend, but it’s still interested to see what will be talked about, and I’ve concocted my own little virtual program out of the main tracks and developers’ rooms. There’s a few minutes overlap between some talks […]
Leon Anavi has spent some time building and running Tizen for Olimex A10s-OLinuXino-MICRO board based onAllWinner A10s cortex A8 processor, and gave a short presentation at FOSDEM 2014 showing the main steps involved in the project. The final result is basically a non-portable Tizen tablet with a main board connected to an LCD display. If you have an LCD screen, you could also use a monitor (VGA/HDMI) instead. After a short description of the hardware, and explaining it should also work on other AllWinner platforms such as Cubieboard, Leon gave a few no-nonsense recommendations he learned from his mistakes: Get a USB serial board for debugging Use recommended accessories from the manufacturer such as power supply or LCD display to make development easier Buy a board that can boot from micro SD or SD card, again for ease of development If something does not work… Restart the board! 🙂 In […]
For those interested, here’s the list of hardware platforms I own [Updated in May 2017): Linux Development Boards Raspberry Pi – Development board powered by Broadcom BCM2835 (ARM11) that supports several Linux distributions Raspberry Pi 2 – Development board powered by Broadcom BCM2836 (4x ARM Cortex A7) that supports several Linux distributions Raspberry Pi Zero – Minimal version of Raspberry Pi board. ODroid-X – Development board based on Samsung Exynos 4412 Quad core cortex A9 processor for Linux and Android development – See unboxing and Android review. Cubieboard – Development board featuring AllWinner A10 processor. Read Unboxing and quick start post for details. Olimex A13-OLinuXino-MICRO – Open source hardware AllWinner A13 development board. Read my board review for details. Wandboard Dual – Development board powered by Freescale i>MX6 Duallite processor. See unboxing and quick start guide. My short Ubuntu review may also be interesting. OPENBRIX Zero – Development board based on […]
