$49 Dashbot Car Dashboard Assistant is Powered by C.H.I.P Pro Allwinner GR8 Module (Crowdfunding)

Most companies specializing in development boards may sell a few accessories for their boards, but usually leave product design to their customers. Next Thing Co. does that too, but the company also produces some products like PocketCHIP portable Linux computer & retro game console, and more recently Dashbot, a voice controller assistant for your car’s dashboard powered by CHIP Pro module. Dashbot hardware specifications: CPU Module – CHIP Pro with Allwinner GR8 ARM Cortex A8 processor @ 1.0 GHz, 512MB NAND flash, 256 DDR3 RAM, 802.11 b/g/n WiFi, Bluetooth 4.2 External Storage – micro SD slot Display – Red LED display Audio – 32-bit audio DSP for beamforming & noise suppression; fairfield audio pre-processor with 24-bit ADC; high fidelity MEMS microphone array (106 dB dynamic range) USB – 1x USB host port Power Supply – 5V via USB port or 12V via power port (aka cigarette lighter) + backup LiFePo4 […]

Make-WiFi-Fast Project Massively Improves WiFi Performance of Busy WiFi Routers

WiFi is a great way to add connectivity to a large group of people, but once everybody tries to connect at the same time, the network often becomes unusable due to very high latency, a problem that can occur on servers on the ISP side too, and that’s usually caused by excessive buffering, Bufferbloat. The Bufferbloat project aims to resolve this issue with both routers using CoDel and fq_codel algorithms, as well as WiFi via Make-WiFi-Fast project. Dave Täht gave a presentation of his work on Make-WiFi-Fast project entitled “Fixing WiFi Latency… Finally“showing how latency was reduced from seconds to milliseconds. It’s quite technical, but two slides of the presentation clearly shows the progress made. The first chart shows 100 stations connecting to a website using unpatched code with the top of the chart showing the bandwidth per node in MBits/s, while the lower part showing latency in ms. We […]

Banana Pi M2 Ultra Allwinner R40 Development Board with SATA & GbE Sells for $46

Allwinner A10 and A20 processors have been quite popular in the past since they could handle Fast or Gigabit Ethernet and SATA natively, included decent multimedia capabilities, and were found in low-cost hardware such as Cubieboard 2 or MeLE A1000. Since then we’ve had a few boards with SATA using newer and faster processors without SATA IP, meaning it was usually implemented using a USB 2.0 to SATA bridge leading to mediocre to average performance depending on the implementation and selected bridge. Allwinner R40 is the successor of Allwinner R20 with a faster quad-core Cortex A7 processor, but keeping Gigabit Ethernet, SATA, and most features of its predecessor. The good news is that Banana Pi has now launched the promised M2 Ultra development board based on the new processor for $45.80 + shipping on Aliexpress (Total for me: $48.35). Banana Pi M2 Ultra specifications: SoC – Allwinner R40 quad-core ARM […]

Allwinner H2 Linux & Android SDK, and Allwinner XR819 WiFi Driver Released

Orange Pi Zero is an interesting little ARM Linux board thanks to its low price, but also because it features a new Allwinner H2 / H2+ quad core Cortex A7 processor very similar to Allwinner H3 minus the 4K video decoding part, as well as Allwinner XR819 WiFi module, which I have not seen on any other boards so far. But hardware without software is pretty much useless, so developers will be happy to find out that Allwinner H2 SDK with Linux (lichee) and Android has been released or leaked, and it also includes the Allwinner XR819 WiFi driver. You’ll find the SDK on Zoobab server with three main directory / files: Android folder – Android 4.4.2 SDK lichee folder – Linux 3.4.39 source code. However you’d probably better use Linux 3.4.113 currently released by sunxi-linux, or Linux mainline. The latter does have some limitations, and may or may not […]
