Orange Pi 3G-IoT Board Finally Gets a Linux Image

Orange Pi 3G-IoT Linux

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 distribution used, or whether the company used buildroot or the …

Orange Pi AI Stick 2801 Neural Compute Stick SDK & Documentation Released

How to use Orange Pi AI Stick SDK

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, and $149 for the software tools. The company further explains …

$69 Orange Pi AI Stick 2801 Features Lightspeeur 2801S Neural Processor

Orange Pi AI Stick 2801

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 AI Stick 2801 specifications: ASIC – SPR2801S Lightspeeur series processor …

How to Build an Orange Pi Zero LoRa Gateway

Armbian 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 Armbian 5.38 on the board, and setup the timezone and …

Orange Pi 3G/4G Cellular IoT Development Kits with Touchscreen Display Launched for $35 and Up

Orange Pi 4G-IoT Set5

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 Pi 3G-IOT-B board powered by Mediatek MT6572 dual core Cortex …

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 over. That was what happened for 4.0, after all. As …

Orange Pi 3G-IoT SBC Launched for $24.90

Orange Pi 3G-IOT

We had two Arm Linux SBCs with cellular connectivity from Shenzhen Xunlong so far: Orange Pi 2G-IoT for 2G connectivity, and Orange Pi 4G-IoT with LTE support in Asia and Europe. But what if you needed 3G connectivity, and did not want to spend $45 on the 4G board? There was no option until today, but the company has just launched Orange Pi 3G-IoT with WCDMA (UMTS), TD-CDMA and CDMA2000 support. Orange Pi 3G-IoT-B board specifications: SoC – MediaTek MT6572 dual core Cortex A7 processor @ up to 1.2 GHz with Arm Mali-400 GPU System Memory – 512MB DDR2 Storage – 4GB eMMC flash, micro SD slot Display I/F – FPC connector for FWVGA display (854×480) Camera I/F – MIPI connector Audio – 3.5mm audio jack, built-in microphone, 2x solder pads for optional speakers Connectivity Cellular Nano SIM card slot 2G GSM – 850/900/1800/1900 MHz 3G WCDMA -(B1/B2/B5/B8), TD-CDMA, CDMA2000 WiFi, Bluetooth, FM and GPS all in one USB – …

Android 8.1 Firmware and SDK Released for Orange Pi 4G-IoT Board

Orange-Pi-4G-IoT-Android-8.1

When Orange Pi 4G-IoT board launched a few months ago, it shipped with a not so recent Android 6.0 operating system. But the good news is that Shenzhen Xunlong Software has now released Android 8.1 firmware for their Mediatek MT6737M quad core Cortex A53 LTE Cat 4 board, as well as the corresponding SDK. This makes it the cheapest Android 8.1 board with LTE connectivity available on the market so far as it goes for just under $50. The SDK is a large tarball (22.6 GB) split into 11 smaller files. It’s hosted on MEGA so download is fairly fast, but due to the size I had to install MEGA Sync software in order to download it easily. Once the download is complete, it’s not recognized in Nautilus, but you can extract the SDK as follows in a terminal: This will take a while and extract over a million files for a total of 64.8 GB. We can now have …
