Orange Pi 2G-IoT ARM Linux Development Board with 2G/GSM Support is Up for Sale for $9.90

Orange Pi 2G-IoT was unveiled at the start of the year as an ultra cheap ($10) Linux development board with 2G cellular connectivity. The board has just launched for $9.90 + shipping on Aliexpress.

Orange Pi 2G-IoT specifications have changed a little since the initial announced as WiFi is confirmed to be supported:

  • SoC – RDA Micro 8810PL ARM Cortex A5 processor @ up to 1.0 GHz with 2Gbit (256 MB) on-chip LPDDR2 RAM, 4Gbit (512 MB) on-chip SLC NAND flash , 256KB L2 cache, Vivante GC860 3D GPU, and GSM/GPRS/EDGE Modem (Download datasheet)
  • External Storage – micro SD slot
  • Display I/F – LCD connector up to qHD resolution
  • Video – Decoding up to 1080p30, encoding up to 1080p30 H.264
  • Audio I/F – 3.5mm audio +FM jack, built-in microphone?
  • Connectivity – WiFi 802.11 b/g/n + Bluetooth 2.1/EDR module (RDA5991), and 2G GSM/GPRS/EDGE module with SIM card slot
  • Camera – MIPI CSI-2 connector for camera sensor up to 2MP
  • USB – 1x USB host port, 1x micro USB OTG port
  • Expansion – 40-pin GPIO header with SPI, I2C, ADC, GPIOs, PWM, etc…
  • Debugging – 3x pin UART for serial console
  • Misc – 8 selection jumpers, power button, boot selection header
  • Power Supply – 5V via micro USB port; optional battery
  • Dimensions – 68 x 42 mm
  • Certifications – CE and FCC (if we can believe the markings on the PCB silkscreen)

Linaro showcased Ubuntu on the similar Orange Pi i96 board at Linaro Connect Budapest 2017 last month, but I have not been able to find an image, nor source code yet. Needless to say, beginners better wait before buying this board, as everything is new, and software support is unclear at this stage. You’ll also have to check 2G sunset status in your countries, as some have stopped supporting 2G already, while others plan on keeping 2G networks for many more years.

Thanks to OvCa77 for the tip.

    Do note that if you are in the USA the 2G network is in the process of being shut down and the bandwidth is being redeployed for LTE use. I believe it is supposed to be completely turned off on all carriers within two years. AT&T has already shut down their 2G network. They told 200,000 paying customers, tough luck, we’re still shutting it down.

    For USA LTE-M is best for future deployments. Can we get a $10 LTE-M board?

    Is Orange Pi taking on FriendlyArm competitively? The pricing of this board and the recent H5 Zero product seem aimed right at FA.

    Orange Pi should be worried about Friendly because they do support much better than OPi does. FriendlyArm is underrated and underappreciated, IMHO. I have a FriendlyArm NanoPi NEO and I’m quite pleased with the Ubuntu core image, the available Wiki, the available schematics and other docs, support forums where the company employees seem to appreciate customer feedback.

    Verizon is promising LTE M hardware for as little as $6.

    β€œI expect this price to go below $8 and maybe over time to approach … $6,” Karam said. β€œWith this Cat-M what you are trying to do is make a solution that is really as cheap as a 2G solution, and 2G is really today in the $6 range. Cat-M is replacing 2G because 2G is [being]refarmed and Cat-1 is replacing 3G.”

    http://www.rcrwireless.com/20160216/internet-of-things/lte-iot-sequans-cat-m-verizon-tag4

    You can buy modules with those Sequans chips right now, but the modules are $70 Not sure how to achieve that $6 price point. Maybe CNX can ask them how?

    I be even happier if the cell carriers deployed SigFox on their cell towers since I can use off-the-shelf $3 radios with it. But we all know cell companies are all about maximizing their own profit and customer needs are a minor concern.

    Cat M1 (also called LTE-M) is also a licensed-spectrum solution, and, in addition to reaching the market before NB-IoT, it does have some performance advantages over that recently standardized technology. However, pricing may keep Cat M1 from gaining the competitive edge it needs. According to Verizon, the company plans to offer $2-per-month data plans for Cat M1-connected devices, with additional options available for volume purchasing. In contrast, Actility estimated at the LPWAN conference in Paris last week that average costs across the market for devices connected to low-power, wide-area networks are closer to $1.

    LTE M is another game altogether!

    Pycom has pre-orders (May/June deliver) for their G01 modules with an ESP32 WiFi/Bluetooth micro + Sequans module for about €24: https://www.pycom.io/product/g01-oem-module-shipping-may-2017/

    They’re also about to ship the FiPy board with the ESP32 micro + Sequans LTE CAT M1 / NB1 module + LoRa and Sigfox (both via Semtch SX1276 chip) very soon at €49: https://www.pycom.io/product/fipy-preorder-shipping-april-2017/

    I think $6 for the Sequans module alone in large quantities isn’t too far off.

    Another strange animal from Xunlong, this time not even Allwinner πŸ˜‰

    1. Can a CVBS/ AV port, more flash/ RAM, mic/speaker ( if not already) and a DC jack be attached on a cheap shield, similar to the $2 shield for the ill fated OPi0?

    SD cards are slow and most people regret buying cheaper ones later. eMMC will standardize and be cheaper. No harm with both options that all xPi vendors ought to consider.

    2. Can an Ubuntu distro (or Android 4.4.4) fit in 512MB flash and have room for apps including NodeRed and MQTT etc?

    3. Maybe the WiFi- BT antenna can be used to stream from cam/ USB port to a Miracast TV dongle (likely requiring HW acceleration), while the 2 G modem can do IoT over the Internet with or without Cloud storage.

      http://www.mobilesdirect.in/40300/videocon-v40ld-512-mb-black

      So hopefully Xunlong might have less software support headaches here. That XR819 on OPi0 is still a fail, rebranded by some loudmouths as “low end, to be fixed with the new driver.”

      The 2G SIM idea is quite nice for $10. A 2G dongle alone looks like $6, about same cost as for a 3G dongle, without the integration.

      So this could be a better deal than the $8 WiFi Lichee Zero, which seems to promote its IoT and LoRA modules more than the Zero.

    So 3.10 is confirmed. 3.10 LTS was already EOL at the end of last year and only due to a kind soul taking over maintainership it will be EOLed now in October.

    And there’s also a difference how to deal with these BSP kernels: Taking mainline of same version, then import BSP stuff to have an idea what the hardware vendor has changed (auditing) and then simply apply mainline kernel branches. Or you just take the BSP kernel as it is and apply mainline patchsets. That way you might fix some CVEs but things like Allwinner’s ‘rootmydevice’ will be discovered later or never.

    Just had a short look into the 2G_IOT_Ubuntu1604_Server_V0_5 thing and already deleted everything. Partition table already tells us that this is just an Android image with an Ubuntu userland:

    As usual parted starts to complain about ‘backup GPT table is corrupt’ and so on (the usual stuff when dealing with OS images that fell out of Android BSPs). It’s an armhf ‘16.04.1 LTS (Xenial Xerus)’ userland with an ‘3.10.62-rel5.0.2’ Android kernel started by u-boot ‘2012.04.442-rel5.0.2’ so most probably no 3rd party software support ever πŸ™‚

    Fortunately I’Almost forgot. That’s the rootfs:

    A ‘little bit’ too fat to fit into the 512MB flash. Fortunately a lot of scripts are in /usr/local/ (many of them from loboris who made the first H3 based Orange Pis useable) and one of the first tasks should be rootfs expansion by running loboris’ fs_resize script.

    The OS image seems to be either loboris’ Ubuntu Mate 15.10 upgraded to Xenial (/boot is full of garbage only useable with H3 legacy kernel) or just a weird mixture of anything (apt history starting at 2016-11-07 but ‘/home/orangepi/.bash_logout’ from 2015-09-01). And bash_history proves that this userland was also used on an OPi Zero before:

    Well, at least I know why I only trust in OS images completely made from scratch πŸ™‚

    Depends. There’s something called ‘Boot selector’ on the PCB so you might be able to transfer an OS image from SD card to the SLC flash, then adjust this and boot happily from a different device with the partition still being /dev/mmcblk0p7. But obviously not with this OS image since too fat.

    Time will tell, at least I lost any interest in this platform some hours ago after checking kernel version and the state of the OS image (could’ve been fun to play with even if I totally lack use cases for this board… OPi Zero is the way better choice for me).

    As usual most users don’t give a sh*t about kernel version, security and the like so I really hope for both customers and Xunlong that the quality of this OS image is better than it seems.

    Addendum: it’s rather easy to take this overweight Ubuntu image, throw the userland into the bin and replace it with a random armhf OpenWRT/LEDE userland. Then it would easily fit into the SoC’s flash but no one right in his mind would spend time on this since smelly kernel and stinky OS image format (being an Android with exchanged rootfs) so this is something you would need to hire someone for (I’m a bit surprised that this hasn’t happened but maybe it just needs some patience)

    Good idea but I wonder why Xunlong’s software guy didn’t do that already? If there are sources available stuff like this should be rather simple, if not even trivial fixes will be impossible. BTW: I also forgot to look whether/how Wi-Fi would be enabled on this OS image (in the past sometimes it took months until such ‘features’ became available on the official images). I also forgot to check the ‘fs_resize’ script since if it’s not modified it will fail dealing with mmcblk0p7.

    Now sales exceeded 700 pieces already, I wonder how many of the buyers aren’t aware that software might be a problem for the first weeks or maybe ever…

Using the serial connection on the three pin header and minicom in LOGmode I was able to make an ls -lR of the root directory, dumps of the flash images. Initially it was spewing a lot of data, but after some 15 miniutes it got quiet. With ‘su’ i could reach root level and with cat *.rc all init scripts were read.

    Instead of manually editing files, another way of configuring Wifi from the command line is to use nmcli or nmtui.
    For nmcli see beginning of http://www.cnx-software.com/2017/02/19/how-to-use-chip-board-as-a-linux-printer-scanner-server/
    Not tried nmtui myself. See manpage -> http://manpages.ubuntu.com/manpages/wily/man1/nmtui.1.html

    @cnxsoft
    Well, nmtui is just the single step variant of nmcli suited for most common tasks. You can either choose your SSID from a list or if you know it already (or it’s ‘hidden’ — funnily still people do this BS in 2017) you then do just ‘nmtui-connect SSID’, enter the password and you’re done. Way too easy!

    People fear this would be worse than editing plain text files. Well, both nmcli and nmtui just create a ‘profile’ below /etc/NetworkManager/system-connections/ which is such a plain text file but only readable by root (so unlike the irresponsible /etc/network/interfaces approach now your Wi-Fi credentials are not world readable). You can take this file and throw it at the same location of another machine and ‘it just works’ even if the Wi-Fi interface there is named differently. Again that’s way too easy.

    For testing purposes I did it exactly that way a while ago with my Armbian builds: throwing in /etc/NetworkManager/system-connections/Snort-Honeynet profile automated in every newly built image just to realize that I later f*cked up some networking tests since I fiddled around with a new board that was not even connected to Ethernet.
