3.95 Euros RPI-UEXT Breadboard & UEXT Adapter for Raspberry Pi is Now Available

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 Pi controlling the 4 relays on MOD-IO. The Linux instructions […]

Nvidia Tegra 4 to Feature 4 Cortex A15 Cores, 72 Graphics Cores

According to Nvidia Tegra roadmap, the first Tegra 4 (T40) is due in Q1 2013, before T43 & AP40 come out in Q3 2013. Information is still sparse, but somebody posted a leaked slide on Chip Hell which gives a few more details about the upcoming Tegra 4 processors. So this is what we currently know about the Tegra T40 processor: CPU – 4x Cortex A15 (Eagle) cores @ 1.8 GHz + a battery saving core (aka companion core). GPU – Geforce GPU with 72 cores providing 20x Tegra 2 performance and 6x Tegra 3’s. Memory – Support for DDR3L, LPDDR2 and LPDDR3 Video – 1440p video encoding and decoding with VP8 and H.264 High Profile hardware acceleration Display –  2560×1600 24-bit, 1080p @ 120Hz, 4K displays via DSI and HDMI interfaces. Power – Lower power than previous generations thanks to 28nm HPL process (low power with high-k metal gates). Tegra 4 will also feature a 5th core and PRISM (Pixel […]

Rhombus Tech EOMA-68 CPU Card Prototype

Do you remember Rhombus Tech AllWinner A10 EOMA-PCMCIA CPU card that targets a BOM cost of $15 US, that was announced at the end of last year? Well, after much wait, the first prototype is now available. This CPU module is based on AllWinner A10 Cortex A8 processor, with 1GB RAM, a NAND Flash, one USB OTG port, microSD slot, HDMI, PMIC, an Ethernet PHY (at the back), an expansion header, and the EOMA-68 connector giving access to peripherals signals (SATA, Ethernet, RGB/TTL, I2C etc…). It can act as a Linux/Android stand-alone computer or be connected to a baseboard. One of the first project will be a laptop for the Chinese market. AllWinner A10 SoC may be a little underpowered to be used in laptop compared to the latest ARM processors, but since EOMA-PCMCIA is a standard, pin-to-pin compatible modules will eventually be designed and manufactured with different/faster (ARM) processors. New modules are expected to be designed much faster than […]

libavg on Raspberry Pi

libavg development team has recently announced a beta port of their multimedia library to the Raspberry Pi. libavg is a high-level development platform for media-centric applications using Python as scripting language and written in C++. I came to know this platform as I tried Xibo Digital Signage, and I tested it on ARM platforms. Up to know this would only work using software rendering/decoding, and everything was painfully slow on ARM, but libavg developers are now making use of OpenGL ES to boost graphics speed. More work is needed, and they intend to eventually support features such as hardware video decoding (OpenMAX possibly via gstreamer) and compressed textures. Installing libavg on Raspberry Pi. Pre-built packages are available for Raspberry, so installation is pretty straight forward: Running Samples Apps 32 samples are located in /usr/local/lib/python2.7/dist-packages/libavg/samples/ directory, and they rely on X11, so first start LXDE: Open a serial console (LXTerminal) and run one of the sample: This will show a smoothly spinning […]
