Orange Pi 4G-IoT Development Board Launched for $45

Orange Pi Development Boards

Last year, Shenzhen Xunlong Software launched Orange Pi 2G-IoT board for just $9.90. Pricing was incredibly aggressive for a cellular board, but AFAIK the RDA Micro processor used in the design had never been used with Linux so for many people using the board was a challenge (and maybe still is), and some countries have already started to sunset 2G networks.

So it only made sense for the company to work on a 4G board, and that’s exactly what they have done with Orange Pi 4G-IoT now launched for $45 + shipping on Aliexpress.

Orange Pi 4G-IoT specifications:

  • SoC – Mediatek MT6737 quad core Cortex A53 processor @ 1.1/1.3 GHz with Arm Mali-T720MP1 GPU
  • System Memory – 1GB DDR3
  • Storage – 8GB eMMC flash + micro SD slot
  • Video Output – HDMI, LCD display interface with touch panel support
  • Audio – 3.5mm earphone jack, built-in microphone
  • Cellular Connectivity
    • nano SIM card slot
    • “GSM” antenna + diversity antenna
    • 2G – GSM @ 850/900/1800/1900 MHz
    • WCDMA – B1/B2/B4/B5/B8
    • TD-CDMA
    • CDMA2000
    • LTE Cat 4
      • FDD-LTE – B1/B2/B3/B4/B7/B107/B20
      • TDD-LTE – B38/40/41B
  • Connectivity – WiFi, Bluetooth, FM, and GPS with antenna
  • Camera – 25-pin ZIF connector for 13MP camera
  • USB – 3x USB host ports, 1x micro USB port (only for flashing firmware)
  • Sensors – Accelerometer, fingerprint (how?)
  • Expansion – 40-pin header with 2x SPI, 3x I2C, 2x UART, 1.8V
  • Misc – IR receiver, power key, power and status LEDs
  • Power Supply – 5V/2A via power barrel jack; battery support through “weld plate”
  • Dimensions – 85 x 55 mm

Mediatek MT6737 is a low cost LTE application processor for smartphone, so it’s no surprise the board can run Android 6.0, but for now at least there’s no word about Linux support. As usual, an Orange Pi board with a new processor (in dev boards) should only be suitable for the most adventurous among us 🙂

FDD B2 and B4 — this might actual work in the USA on AT&T, Verizon, T-Mobile.


I ordered one. I have been looking for a phone chassis to OEM for a long time and none of the phone chip vendors would talk to us.

I found the CPU manual.


I wonder if Freeswitch GSM-Open module will be able to run on this. I used it with an Huawei dongle to route calls through VoIP:


Video in this chip is useless – encode 720P MPEG4 at 15Mb/s. No h.264 encode support.
What is the point in having dual 8MP MIPI camera support with no ability to encode it?

Maybe this is a MT6737T? It supports 30FPS 1080P h.264.


Wow, LTE, crazy.

What’s current usage for the board?


Jon Smirl, machine vision or surveillance, perhaps? Not everything is about television.


No battery support is a huge fail, just like with 2G-IOT. Whats the point of such board, if you can’t power it via battery ?


I want to be able to use the camera to remotely view what the device is seeing. The encoder on this chip is too poor to handle reasonable remote viewing of the video. This chip needs 15Mb/s bandwidth for the camera. An h.264 stream only needs about 2Mb/s. They need to switch over to the MT6737T to get a modern h.264 video encoder, not MPEG4 from 2002.


I’m not sure where you’re getting this information, but according to MediaTek’s own website (and my own experience) it can encode h264 at at least 720p60



Video Encoding: MPEG-4
Video Encoding FPS: 30 @ 720p

You must have the MT6737T version which can do h.264


parrotgeek1, do you have a MT6737 or a MT6737T?


I guess this is another rubbish without CE/FCC…


Well good they innovate but Orange Pi always lets themselves down, on software and after support.

Also now they have given themselves two mobile SoC to support, 2g -IoT Soc and this 4G IoT Soc.


My 4G-IOT board has arrived. I powered it on an hooked it to an HDMI monitor. Four monitors later I found one that will work with the odd 720P mode it defaults to. This default needs to be changed to a more common 1080P mode. I have not verified cellular yet since it takes a mini-SIM card and I had to order one. Mouse and keyboard work from the USB port. It is likely that USB Ethernet will also work, but I did not try,

I did download the Android 6 source and it does build and produce an image. I have not tried reflashing the device yet. It implements some Mediatek UI, not the normal Android one. A first project would be to remove the Mediatek UI. Kernel is ancient 3.18 which was EOL in January 2017.

No schematics have been posted yet so I am unsure of what the hardware does. Initially USB OTG did not work and I just guessed and removed J5 to make it work. Once I had adb working I was able to look inside and verify that it really is a MT6737 (not T) and it only has crummy MPEG video encode support (from 2002).

OrangePi has promised a release of Android 8 soon. So I don’t know if I will mess with this Android 6 much. I’d rather work on the newer source.

For my purposes this is just a demo board since it is lacking reasonable camera support. The IOT devices I work on are all cameras.
