A64-OLinuXino update


We just got some more information from Allwinner for A64 and the good news is that it have Gigabit Ethernet interface!

So beside the WiFi + BT 4.0 A64-OLinuXino will have also native Gigabit Ethernet interface :)

We work on A64-OLinuXino the first Open Source Hardware 64-bit development board


A64 was announced January this year by Allwinner. It’s a quad core 64 bit Cortex-A53 processor targeting tablets.

Some features are:

  • H.265/H.264 video decoding in hardware
  • HDMI 4K display support
  • DDR3L memory with lower consumption is supported
  • eMMC 5.0 support

Last week we got notice that Allwinner have already A64 in production and we will get some chips with the software SDK for Android 5.1 based on Linux Kernel 3.10 by the end of the month (yes they finally escaped from Kernel 3.4 :) ), so we started to work on our A64-OLinuXino.

This chip is with humble peripherials, as Allwinner target and announcement is to sell it for $5 in volume (obviously not for mortals as we have to buy the first chips at higher than this price).

  • LCD parallel RGB, LCD LVDS, MIPI and HDMI video output
  • Camera interface
  • One USB Host
  • One USB-OTG
  • Two SPI
  • Four I2C
  • Six UARTs

As you can see no Ethernet, no SATA, no PCIe, but this is what you get for $5 right ?

What we found is also that although being 64-bit ARM the A64 memory bus is just 32-bit wide, we guess to make BOM smaller.

This will hurt the performance, so we have to see how it will behave compared to A20 and H3 for instance.

A64-OLinuXino initial specs will be:

  • A64 4 core Cortex-A53
  • AXP803 PMU + Audio support
  • 1GB or 2GB DDR RAM
  • 4GB NAND Flash oe eMMC
  • micro SD card connector
  • micro USB-OTG
  • 2Mpix Camera on board
  • HDMI 4K output
  • Audio Output, Input
  • LCD connector to connect with all our LCD-OLinuXino 4.3″ 7.0″ 10.1″ 15.6″
  • RTL8723BS WiFi + BT4.0 on board for connectivity
  • GPIO connector with access to all processor resources
  • 5V power input

This will be our first 64 bit ARM board and also the first OLinuXino we make completely with KiCAD.

If everything goes smoothly we will have first prototypes by end of November and depend on how fast we can test the software we may have these run in production for Christmas :) the goal is to make 64-bit ARM with EUR 64 retail price!

As I expect A64 with 4 cores Cortex-A53 will behave well running Desktop Linux so we are evaluating the option to find some Chinese laptop manufacturer and ask them to supply us just with some light laptop body with decent 10.1-11.6″ LCD display, camera and keyboard with touch-pad. We can re-design A64 board to fit inside this laptop body and to make light under 1 kg laptop running Linux.

One of the problem is that A64 is quite new and no any Linux-Sunxi support, as nobody have seen A64 development boards yet. SO it may pass several months until A64-OLinuXino run anything else than Android 5.1

Don’t you love these Internet Surveys?


I love Internet surveys, they are so easy to manipulate :)

Yesterday Drew Fustini posted on G+ the letter he got about one of the few new 64 bit development boards which he ordered.

As you see from the letter this board will go for sale end of November as still didn’t pass necessary tests for FCC – it have cellular modem and WiFi on it.

In one of the comments on G+ post is seen that this obviously do no stop people to choose this same board which probably is sampled just to few developers (Qualcomm gave away few on Linux Con and OpenWRT) as #5 in “Top Ten Hacker SBCs” by LinuxGizmos.com.

So people may wonder how do Hackers evaluated this board and selected is as board of choice if it’s still not even shipped to mass users?
It’s a mystery which Qualcomm PR dept may unveil :)

Fact is that all these Internet surveys are easy to manipulate, so always have a bit in skepticism in mind when you read next “which p@nnis is bigger” survey done on the internet.

ESP8266 update – The Ultimate Development boards for ESP8266 are in stock


ESP8266 already got a lot of attention, but the problem is that this chip has more to offer than just UART to WIFI module, there is C compiler, SDK which allow you to write user program and have access to all GPIOs and resources of the chip so instead to add dumb microcontroller to ESP8266 module you will be able to put all your application in the ESP8266 itself.

The problem is that most existing modules do not allow access to all ESP8266 resources… until now, you see the untilate development board for ESP8266 now, it have access to all ESP8266 resources, GPIOs, bootloader etc.

The module MOD-WIFI-8266-DEV have UEXT connector footprint on the back so it can connect to all OLIMEX boards which have UEXT connectors, two rows of 0.1″ connectors for breadboarding and split pads which could be soldered directly to PCB.


For these who want to use ESP8266 just as SERIAL-to-WIFI bridge MOD-WIFI-ESP8266 is the better choice with smaller size and soldered female UEXT connector it direcly will plug to any board with UEXT.

Both boards are in stockMOD-WIFI-ESP8266 cost EUR 5.00 for single quantity,MOD-WIFI-8266-DEV  cost EUR 5.50 in single quantity.

MOD-WIFI-ESP8266-EVB with Relay, button, Power supply, GPIOs access is in production and will be available in couple of weeks! It have on it MOD-WIFI-ESP8266-DEV on socket.

A80-OLinuXino OSHW 8-core Linux computer development begins

Email banner-ch

Allwinner is about to release soon (end of this month hopefully) datasheet and info about their new 8-core monster processor with 4x Cortex-A15 + 4x Cortex-A7 and here we go and start preparing what to include in the new A80-OLinuXino.

We would love to hear your feedback and recommendation what do you think is important as value and “to have” on board, here are the major features (taken from Allwinner site) :

  • DDR3  standard 2GB, optional 4GB
  • Gigabit Ethernet
  • optional NAND Flash 4GB
  • SD cards x4 possible
  • USB-OTG 3.0
  • USB hosts x2 2.0
  • MIPI camera interface
  • real ADCs x2
  • PWM
  • UART x7
  • I2C x7
  • SPI x4
  • I2S
  • LCD

Unfortunately A80 have no audio on chip so external codec is necessary if you want to have Audio connector how important is this if we already have audio on the HDMI connector?

If we go in to LIME form factor route we have to look just for the bare minimum of connectors due to the space limitation, if we go in max features direction the board will become big and expensive.

Let’s the wishes begin :)
