H3-OLinuXino-NANO update – it work with 8Gb DDR3L too so this small board can have 1GB RAM also

H3-NANO

H3 has dual DDR chip select so when we routed the board connected both to the DDR package but were not sure if it will work, now when we had prototypes decided to replace the 4Gb DDR3L memory with 8Gb DDR3L memory.

The result was success! H3 booted and show 1GB available memory, this means we can assembly 8Gb memory to next revision of H3-OLinuXino which have two chips and have 2GB RAM on it.

The bad news is that 8Gb memories are very new and their prices per chip are almost x4 times more expensive than 4Gb memory chips (i.e. 1GB made with 8Gb chip cost 2 times more than 1GB made with 4Gb chips).

H3-OLinuXino-NANO is only 50×50 mm but has everything one computer must have

H3-NANO-2

Nice to meet you! I am H3-OLinuXino-NANO, ultra small 50×50 mm Linux computer with

  • H3 quad core Cortex-A7 processor
  • 512MB of DDR3 RAM
  • 2x USB hosts for mouse and keyboard
  • Ethernet 100Mb interface
  • HDMI Full HD output
  • 4 buttons
  • micro SD card
  • UART console
  • USB-OTG which also is used to power the board
  • 4 mount holes
  • 2x 40 pin connectors (optional) which carry lot of GPIOs

We now try the software and test all peripherals if everything is OK will proceed with production, but we overall are very proud that managed to shrink in this space the complete board i only 6 Layers.

We learned our lessons from the first H3-OLinuXino prototypes, now this board consumes less power, DDR3L memory is used at lower voltage 1.35V and this helps the processor to not overheat like on our first proto.

Where this board could be used?

  • General purpose Linux computer
  • Digital signage
  • Low cost IoT home node server
  • Android TV box to play games and videos
  • Education

Due to the high integration of H3 SoC the price will be below the price of LIME, but no SATA and LiPo charger.

This design is made with Eagle, we have to make few more improvements before run production and put them on Github.

OLinuXino roadmap 2015 :)

RT5350-OLinuXino-DIN

Many people ask us about what we do with Open Source Hardware OLinuXino project. Indeed we didn’t blog about OLinuXino boards often, but this doesn’t mean we do not have fun and working on them.

So let’s make brief update:

RT5350F – the DIN rail version is already complete and wait for assembly, the issue is trivial the plastic box, it will take us most of the time to complete.

Other OpenWRT boards:

We completed and now prototype MT7620N @580Mhz with some more RAM – 64MB and two WIFI bands 2.4G + 5G and 5 10/100Mb Ethernet and prepare board with MT7620A @580Mhz and little bit more RAM 256MB, x2 Gigabit and x4 10/100Mb Ethernets.

When these will be released – we don’t know, RT5350F software took us about year to get NDA info about WiFi tunning, we don’t know what it will be with MT7620, so do not hold your breath 🙂

Allwinner:

A33-OLinuXino (Quad Cortex-A7) now is complete and on prototype stage, still had no time to check if Linux-Sunxi community have Linux for A33 and at what stage it is.

Now we route H3-OLinuXino (with Quad Cortex-A7 and which have Ethernet and HDMI) and A64-OLinuXino (with Quad Cortex-A53, HDMI, Camera, MIPI/LVDS/RGB, Gigabit Ethernet).

Why we stopped to blog or announce so often the new boards we working on?

Because when we blog that we start working on new OLinuXino board many people start to make commercial plans with them and how they will obtain OSHW designs for free for their commercial idea/project. Sure this have nothing wrong, if some of them didn’t became too impatient, annoying and noisy if the release time do not match their expectations. They forget that we do this for fun and we do not have any firm release dates, so they try any forms of social engineering posting challenging or abusive messages thinking they would influence us somehow this way, well soon or later they realize they can’t but anyway this is annoying for us as we want to work in rest calm environment and enjoy what we do.

We learn while we do this stuff, AM3352 software support took us year and half, we couldn’t find vital info for RT5350F for more than year, I have no idea when MT7620, A33, H3 or A64 will have proper Linux support, so please do not hold your breath, these boards will be released when they are ready, if you are capable to help with Linux on these please let me know, we can send you preliminary prototypes, so we can work together to speed up the release.
