Last month, I wrote about an upcoming T-shaped adapter for the Raspberry Pi that can easily plug into a breadboard, and provides a UEXT connector that can bring new features (RTC, GPRS, sensors, relays…) to the Raspberry Pi via low cost external UEXT modules. Olimex has just announced the RPI-UEXT adapter is now available for 3.95 Euros. To connect RPI-UEXT adapter to the Raspberry Pi, you’ll need to purchase a 26-pin ribbon cable and a breadboard if you don’t have these already. Olimex provides those 2 for respectively 2 & 2.95 Euros. That means a complete set would cost 8.90 Euros. As discussed on my first RPI-UEXT post, what makes this little board really interesting are all the existing UEXT modules (over 20) that bring new features at very low cost. Olimex uploaded a video showing the Raspberry Pi, the RPI-UEXT and the MOD-IO UEXT module connected together, with the Raspberry […]
Build Your Own Freescale i.MX6 Quad Laptop
Andrew Huang (“Bunnie”) and others have been working on an open source laptop based on Freescale i.MX6 Quad processor since June, and they’ve recently got the motherboard. Beside featuring a powerful quad core ARM processor, the design files are also provided, so if you have the right skills and resources you can build it yourself. The open source laptop mainboard (Codename: Novena) has the following specifications: SoC – Freescale iMX6 Quad @ 1.2GHz with Vivante GC2000 GPU System Memory – 64-bit DDR3-1066 SO-DIMM, upgradable to 4GB Storage – microSD boot flash, SATA-II connector for hard drive / SSD, SD card reader and serial EEPROM (for storing crash logs and other bits of handy data). FPGA – Spartan-6 CSG324. It has several interfaces to the CPU, including a 2Gbit/s RAM-like bus. Internal ports & sensors: mini PCI-express slot UIM slot for mPCIx mobile data cards Dual-channel LVDS LCD connector (up to […]
Open Hardware System on Module Project
“JM” has started working on a system-on-module project with the goal “to create a whole range of SoM boards and motherboards that can handle a large number of embedded projects”. He has just released schematics and layout files created with Kicad for a dual NXP LPC1764 SO-DIMM module and the baseboard under GPL3 license. The next goal is to release an AllWinner A10 SoM and corresponding baseboard. Kicad is an open source schematics capture and PCB layout software that can run in Windows, Linux and Mac. If you want to read the schematics or try it out, you can freely download it. In Ubuntu you could just use apt-get:
1 |
sudo apt-get install kicad fped |
The hardware files for the module and carrier board are available here. JM explains that the LPC module and baseboard have already been manufactured and tested, so it could just be a matter of adapting the module for AllWinner A10/A20. […]

Le Labo Citoyen Gasser – Raspberry Pi Based High Precision Pollution Monitoring System
“Le Labo Citoyen” is a recently founded French non-profit organization aimed at “promoting and experimenting with innovating and free technologies for the citizens and the environment”. Their first project is to gather pollution data (NO2, O3, and SO2 levels) in Paris using 2 (soon to be) open source components: Gasser – Self-contained mobile sensor currently powered by the Raspberry Pi ThingStream – Open source IoT datastore which should be similar to iDigi Cloud, except you can just store data in your own server or on “Le Labo Citoyen” servers. Gasser has four main parts: Sensor(s) – Alphasense B4-series sensors (black and red component in the top left of the main box) with accuracy of up to <10 ppb (parts-per-billion). Cost: ~110 Euros. They currently only use the NO2 (nitrogen dioxide) sensor. ADC & Computer – Raspberry Pi (Cost: ~30 Euros) & Delta-Sigma ADC (Cost: ~30 Euros). Communication Medium – Huawei […]
AMLogic Releases U-Boot and Updated Linux Kernel Source Code
AMLogic released kernel 3.0.8 source code for AML8726-MX a few months ago, and yesterday they provided an updated tarballs with the kernel, and for the first time, AFAIK, released the source code for U-Boot. There are 4 new files apparently generated from the (internal) git repository in AMLogic: common-2012-11-20-git-b687495906.tar.gz (108M) – This is the same kernel 3.0.8 release has last time, but with updated code. m1-kernel-android-2012-11-20-git-5d0f6b8e93.tar.gz (103M) – This looks like an older kernel 2.6 for AML8726-M1 only. uboot-master-2012-11-20-git-9b50e9a295.tar.gz (16M) – U-Boot 2010.06 possibly to use with the older 2.6 kernel. Only for M1 & M3 platforms. uboot-next-2012-11-20-git-b0e532795a.tar.gz (40M) – U-Boot 2011.03 for use with M3 and M6 platforms. I’ve already explained how to build the kernel in the previous post, so I’ll focus on U-Boot this time. Ubuntu 12.04 arm-linux-gnueabi- toolchain fails to build U-Boot (uboot-next), so you’ll have to install Sourcery toolchain instead: wget http://openlinux.amlogic.com/download/linux/ARM/gnutools/arm-2010q1-188-arm-none-eabi-i686-pc-linux-gnu.tar.bz2 tar xjvf arm-2010q1-188-arm-none-eabi-i686-pc-linux-gnu.tar.bz2 […]
Freescale i.MX6 Resources: Development Boards, Documentation, Source Code and Tools
Reader “Mark” recently left a comment saying the NDA on Freescale i.MX6 resources was lifted and documentation and source code were now available for the platform. So it’s time for me to look into it, and provide an overview of Freescale i.MX6 features, list available development platforms, and have a closer look at the documentation, source code and tools for the platform. Freescale i.MX6 Processors In 2011, Freescale initially announced 3 processors in the i.MX6 series for consumer, industrial and automotive markets, but added 2 lite SoC in 2012, and there are now 5 members in the family: Freescale i.MX6SoloLite – Single Cortex A9 processor up to 1 GHz with 256KB L2 Cache, 32-bit DDR3 and LPDDR2 memory support, and 2D graphics accelerator (Vivante GC355 + GC320) Freescale i.MX6Solo – Single Cortex A9 core up to 1 GHz with 512KB L2 Cache, 32-bit DDR3 and LPDDR2 memory support, and 2D & […]
