Orange Pi RK3399 development board launched last year, further crowding the RK3399 space. The board did not target the lower end of the market with a $109 price tag, but still came with only 2GB of RAM. Shenzhen Xunlong has now introduced a 4GB RAM version of the board for $99.96, with the 2GB version now selling for $89.38. Both boards can be purchased on Aliexpress. Apart from the RAM capacity, Orange Pi RK3399 “4G” specifications have not changed: SoC – Rockchip K3399 hexa-core big.LITTLE processor with two ARM Cortex A72 cores up to 2.0 GHz, four Cortex A53 cores, and an ARM Mali-T860 MP4 GPU with support for OpenGL 1.1 to 3.1 support, OpenVG1.1, OpenCL, and DX 11 System Memory – 4 GB DDR3 Storage – 16 GB eMMC flash, micro SD card, mPCIe (for mSATA/LTE), and SATA interface Video Output/Input & Display Interfaces 1x HDMI 2.0 up to […]
Linux 4.20 Release – Main Changes, Arm and MIPS Architectures
After Greg K-H handling Linux 4.19 release, Linus Torvalds is back at the helm, and released Linux 4.20 just before Christmas: Let’s face it, last week wasn’t quite as quiet as I would have hoped for, but there really doesn’t seem to be any point to delay 4.20 because everybody is already taking a break. And it’s not like there are any known issues, it’s just that the shortlog below is a bit longer than I would have wished for. Nothing screams “oh, that’s scary”, though. And as part of the “everybody is already taking a break”, I can happily report that I already have quite a few early pull requests in my inbox. I encouraged people to get it over and done with, so that people can just relax over the year-end holidays. In fact, I probably won’t start pulling for a couple of days, but otherwise let’s just […]
Orange Pi 3G-IoT Board Finally Gets a Linux Image
Shenzhen Xunlong has launched several cellular IoT boards over the last few years with Orange Pi 2G-IoT, Orange Pi 3G-IoT and Orange Pi 4G-IoT, but each time, they are launched with Android support only. Linux support on the 2G board has never been great, while the Android 8.1 SDK for Orange Pi 4G-IoT was released earlier this year, but no Linux image are available. This leaves us with Orange Pi 3G-IoT board that just got its first Linux based firmware images released today on both Baidu and Google Drive cloud storage storage services. Four images are available for Orange Pi 3G-IoT-A (256MB DDR2) and Orange Pi 3G-IoT-B (512MB DDR2) boards with images booting from eMMC flash or micro SD card. A shell script (tar_image.sh) is provided to flash the image to the micro SD card since the latter for follow a specific partition layout. Sadly, there’s no mention of the […]
Orange Pi AI Stick 2801 Neural Compute Stick SDK & Documentation Released
We covered the launch of Orange Pi AI Stick 2801 neural compute stick a few days ago, the first easily available Gyralcon Lightspeeur based USB stick, and noted that while the hardware was there, we had no details about software development kit and documentation at the time. I’ve got some more information now. First, the company release an English presentation about the neural stick, and while it’s not technical documentation, it provides insights into what it is capable of, and an overview about the workflow. More importantly, Shenzhen Xunlong Software also released Orange Pi AI Stick SDK and user manual for x86 PC, as well as cat/dog data and pre-trained models to get started. However, if you want to perform training with your own data, you’ll need to purchase the stick plus PLAI model transformation and training tools sold on Aliexpress for $218 plus shipping, that’s $69 for the hardware, […]
$69 Orange Pi AI Stick 2801 Features Lightspeeur 2801S Neural Processor
Intel is not the only company selling neural compute sticks to accelerate artificial intelligence workloads at low power, as Gyrfalcon introduced their Laceli AI Compute Stick based on their own Lightspeeur 2801S matrix processor earlier this year, but it was not exactly easy to buy. Even the company’s latest PLAI Plug USB3.0 dongle (new name for Laceli AI Compute Stick?) and PLAI WiFi AI wireless accessory announced just a few days ago are not that easy to purchase, as they require you to fill a form with your project details before being able to buy anything. But thanks to Shenzhen Xunlong Software, the Orange Pi boards maker, it’s now much easier to experiment with the technology since they launched Orange Pi AI Stick 2801, based on the same Lightspeeur 2801S ASIC found in PLAI Plug, but sold directly on Aliexpress for $69 plus shipping ($73.97 in total here). Orange Pi […]
How to Build an Orange Pi Zero LoRa Gateway
LoRa gateways tend to be fairly expensive, especially because of the radio part, but anything that may help lower the cost is probably welcomed. And one way to to do that is to use dirt cheap boards like Orange Pi Zero as Edzelf did, by combining the low cost Arm Linux board ($15 shipped) with Rak wireless RAK831 concentrator module kit ($143) via a custom cable, and a power supply board. All assembled into a metal case. RAK831 communicates with Orange Pi Zero over an SPI connection. While some other Orange Pi boards are suitable for the project, note that Orange Pi Zero Plus lacks a spare SPI interface, and can’t be used with this particular application. A fan was also added for cooling, a well as a USB serial debug board for debugging purpose, but it can be removed once the gateway is in the field. Software-wise, Edzelf installed […]
Orange Pi 3G/4G Cellular IoT Development Kits with Touchscreen Display Launched for $35 and Up
Earlier this year, Shenzhen Xunlong introduced two new Orange Pi cellular IoT boards running Android – but no Linux distribution just yet – with Orange Pi 3G-IoT and Orange Pi 4G-IoT boards, with LTE bands suitable for Asia and most part of Europe, but not the US. But boards are quite cheap, the 4G-IoT model recently got Android 8.1 Oreo support, if you’d like a display with the board, you can now buy various kits with touchscreen display and in some sets a power supply as well for $34.80 and up plus shipping, or the displays only for $14.80 and up. Four kits have been launched so far: $34.80 Orange Pi 3G-IoT-A Set1 with Orange Pi 3G-IOT-A board powered by Mediatek MT6572 dual core Cortex A7 processor + 256MB RAM/512MB eMMC combo chip, and a 4.98″ TFT LCD touchscreen display (854 x 480) $39.80 Orange Pi 3G-IoT-B Set1 with Orange […]
Linux 4.17 Release – Main Changes, Arm & MIPS Architectures
Linus Torvalds released Linux 4.17 last Sunday: So this last week was pretty calm, even if the pattern of most of the stuff coming in on a Friday made it feel less so as the weekend approached. And while I would have liked even less changes, I really didn’t get the feeling that another week would help the release in any way, so here we are, with 4.17 released. No, I didn’t call it 5.0, even though all the git object count numerology was in place for that. It will happen in the not _too_distant future, and I’m told all the release scripts on kernel.org are ready for it, but I didn’t feel there was any real reason for it. I suspect that around 4.20 – which is I run out of fingers and toes to keep track of minor releases, and thus start getting mightily confused – I’ll switch […]
