ARBOR Introduces SOM-RP301 Rockchip PX30 SoM for Retail Kiosks

Rockchip PX30 is a quad core Cortex-A35 processor with a dual VOP (Video Output Processor) in order to drive two independent displays, that has low power consumption, low thermal requirements, and that we previously found in some car infotainment systems. But the processor is also suitable for other applications, and ARBOR Technology recently launched SOM-RP301 system-on-module based on the PX30 processor, and specifically designed for fanless retail kiosks such as electronic restaurant menus, automated currency exchange machines, ticketing kiosks and more. SOM-RP301 system-on-module specifications: SoC – Rockchip PX30 quad core Cortex-A35 processor @ 1.5 GHz with Arm Mali-G31 MP2 GPU System Memory – 1GB LPDDR3 (Up to 4GB as option) Storage – 16 GB eMMC flash Connectivity – Fast Ethernet transceiver, 802.11 b/g/n/ac WiFi 5 + Bluetooth 4.0 module Edge Connector – SO-DIMM connector with Display – LVDS or MIPI DSI Camera – MIPI CSI RX interface with 8MP ISP […]

Introducing CNX Election Meddling System

We love what we do at CNX Software, covering news, product launches, reviewing various types of boards and devices related to embedded systems. But we are also trying to expand our readers’ and our own horizon, always on the look out for unmet market needs that may be filled by the community at large. A few years ago, we found out that while democracy was all good, about people power and blah blah, it could create severe mental stress to the losing side, with talks of dark days for democracy, the end of the country as we know it, and so forth and so on. So we thought about ways to either help change the election outcome, at least lower the blow by making people feel they did the best they could possibly do beside just throwing a piece of paper in a box. That’s why we came up with […]

ClearFog ITX Workstation May be the Ultimate Arm Developer Platform

Most people are still doing Arm development work on x86 platforms, because there aren’t really any viable equivalent in the Arm world. Current options include Edge Server SynQuacer E-Series (aka Linaro Developer Box), a $1,250 Arm PC shipping with a 24-core Arm Cortex-A53 processor, 4GB RAM (by default), a 1TB hard drive, and Geforce GT710 graphics cards, as well as the much more powerful GIGABYTE ThunderXStation workstation with up to two Cavium ThunderX 32-core Armv8 processors, 32GB to 128GB RAM configuration, NVMe storage, and more. The former was a good place to get started, but the Arm Cortex-A53 cores clicked at 1GHz provided limited performance, and the GIGAGYTE workstation costs over $12,000, so it’s only suitable for projects with specific needs and/or a high expected return on investment. That’s why there will be a discussion about Designing a next generation ARM Developer Platform at Linaro Connect 2019 next week in […]

PINE64 Plans to Move their Website on a 24-node RockPro64 Cluster

Boards’ clusters are always fun to see, and PINE64 has shared pictures of two RockPro64 clusters with respectively 48 and 24 boards neatly packed into partially custom enclosures. The 48-node cluster will feature a total of 288 cores, including 96 Arm Cortex-A72 cores and 188 Cortex-A53 cores, as well as 192GB of LPDDR4 RAM. Low cost development boards may be seen as toys by some, so it’s interesting to learn that PINE64 plans to move their complete website infrastructure including the main website, a community website, forums, wiki, and possibly IRC on the 24-node cluster, while it seems the 48-node cluster may be used for their build environment. The company has just completed the assembly of the clusters, and did not disclose the full technical details just yet. However, a progress report may be written in due time. Once the migration is done, and everything works as it should, it […]

Ultra96-V2 96Boards AI Platform Adds Certified WiFi, PMICs, Industrial Temperature Range

Avnet Ultra96 was unveiled last year as one of the four 96Boards AI platforms designed to develop applications leveraging hardware to accelerated artificial intelligence workloads. The 96Boards CE compliant board comes with a Xilinx Zynq UltraScale+ MPSoC, 2GB RAM, a 16GB microSD card, WiFi and Bluetooth connectivity and more. The company has now launched an upgraded version with Ultra96-V2 featuring most of the same specifications but with a WiFi & Bluetooth module certified in 75 countries, industrial temperature range, and Infineon’s PMIC’s for additional power control and monitoring. Ultra96-V2 specifications: SoC – Xilinx Zynq UltraScale+ MPSoC ZU3EG A484 with four Cortex A53 cores, two Cortex-R5 core, Arm Mali-400MP2 GPU, and FPGA Fabric System Memory – 2 GB (512M x32) LPDDR4 Memory Storage – 16 GB MicroSD card + adapter pre-loaded with PetaLinux environment Video Output – Mini DisplayPort (MiniDP) Connectivity – Microchip ATWILC3000 certified 802.11 b/g/n WiFi 4 / Bluetooth […]

ODROID-N2 GPU Drivers, Linux 5.0, and Impressive glmarks-es2 Score

ODROID-N2 was announced last February for $63 (2GB RAM), and $79 (4GB RAM), but Hardkernel was not quite ready to take orders at the time. One of the good news is that the 4GB RAM is now available for pre-order with shipping scheduled to start on April 3. Another good news is on the software side with Hardkernel having released the userland Mali-G52 Wayland driver. It does not work well with Linux 4.9 due to incomplete DRM implementation, but it goes work with Linux 5.0 plus some modifications as further discussed in the aforelinked forum thread. The screenshot above, courtesy of odroid forum member memeka , shows ODROID-N2 running Ubuntu 18.04 + Gnome3 + Linux 5.0 on top of Wayland with GPU drivers providing acceleration as shown by glmark2-es2-wayland test program. The benchmark results are pretty impressive:
