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).

Young hacker playing with Olinuxino boards

We just got this picture :) This small lady from Belgium is picky about her toys. A13-OLinuXino is in her play box.

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

H3-NANO

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.

FOSDEM 2016 was last weekend with lot of interesting meetings and talks!

FSDM

FOSDEM 2016 was last weekend in Bruxelles! Biggest event in EU this year had a bit less visitors, probably feared by the terrorist news which all TVs are exposing us.

Belgians seems to take this threat seriously as we have seen lot of peoples with automatic guns in military uniforms walking around the city center, but fortunately at FOSDEM we didn’t saw any, neither someone has stop us to check or whatsoever while we have been waling in the city.

Some 8000 different MACs were logged on WiFi infrastructure, so I guess at least 5000 visitors were there.

The picture above shows my captures from the event, buying t-shirt was my way to say thanks to these projects which we use daily both at home and office!

You know you have been at FOSDEM Friday beer party when you wake up next morning and you see (hopefully not permanent) “IloveFS” tattoo on your arm. Here is how the Delirium beer hub was looking like at Friday:

I had lecture about our experience designing A64 board with KiCAD, Riku Voipio took picture of the tail to enter the room and posted on G+

fsdem

The slides are posted at Slideshare. TL-DR; KiCAD now is solid enough to build complex designs, what we need is little bit of twist to make it even more easy to use and few minor bugs are to be wiped, but overal there is significant progress for one year!

To my surprise KiCAD team emailed me next day and we had a quick meeting with notes they took on all issues I mention on the talk! It’s nice to see such commitement to make the product better!

Another interesting talk in same EDA room was from Clifford who reverse engineered the iCE40 bitstream and made completely FOSS FPGA toolset, which can be used to generate iCE40 based FPGA projects.

I had eye on iCE40 since Antti Lukats posted on Hackaday about his project, but we were quite busy with many other things to may play with it, now we start working on our own ICE40HX1K development board with UEXT for programming by OLinuXino and different extension connectors. The idea is to make entry level board for people who want to make their first steps in FPGA, running Clifford’s toolchain on OLinuXino with this FPGA board connected to it and with different front-end modules like high speed ADCs to make DSO or programmable level shifter 1.2-5.5V which to allow logic analyzer working on different voltage levels, LEDs, buzzers, counters, buttons with tons of examples. I already shoot Clifford e-mail about our plans and looking forward to hear his suggestions as he already have lot of experience with these FPGAs.

Clifford’s work sparkled such interest for iCE40 that now the Lattice demo boards are with 21 weeks delivery time, plenty of time for us to release our own board :))))

Another interesting lecture was about the Rad1o badge for CCC. It was fun to learn for all the difficulties which the development team had to make these happen (including mistakes in the documentation which made them to drill back side of BGA PCB to disconnect solder ball) – they said they would never go through the manufacturing hell again as this production caused them gray hairs although the interest about this badge continues.

Being busy all day long with both design and manufacturing, once I made analogy about the path to design board and then to run this board in production -> it’s like the process to make kid and then to rise it, teach it, make it human being. First job (design) brings just fun, joy and satisfaction, the second is not less interesting but dealing with all manufacturing bugs and troubleshooting the processes is kinda routeen and sometimes even boring :))) but neverthless must be done! Sure we enjoy more designing than manufacturing, but can’t run sustainable business without latter.

Friday Free Board Quiz – the prize is RT5350F-OLinuXino – Is there anything wrong with this circuit?

RT5350F-OLinuXino-1

RT5350F-OLinuXino is OSHW board which run openWRT Linux distribution and have WiFi.

You can win this board! To participate in the Quiz is enough to re-tweet the Twitter Quiz announcement message.

To double your chances you have to answer the Quiz question :)

The Quiz question is: Is there anything wrong with this circuit?

SCHEMATIC

You have time to re-tweet and/or answer until Monday 1st of February.

In Monday we will post the correct answer and ask random.org to generate random number in range then announce the winner and ship the board by post/airmail.

Good Luck!

REDS.box – Home cloud server based on A20-OLinuXino-LIME on Kickstarter

695e2a57a3b7a3d480c4ad9939de2544_original

REDS.box is new Kickstarter project which use A20-OLinuXino-LIME to create your own home server to keep your files safe and available on the net.

1d18e041ad78a28983aa1b8dddc4cd9a_original

People who use a cloud app these days have to store their data on servers of the companies that provide the app. Without knowing what will happen to your data and who else has access to it, you are asked to trust those companies – which means you are losing control over your data and privacy!

With REDS.box you know exactly where your files are – on your own server where only you have the access rights.

 

Quiz Answer: There is no standard 17K resistor in any tolerance :)

resistor-color-chart

17K value doesn’t existi in any tolerance So no such standard color code :)

It was fun to see how such easy question can mislead so many people!
