While we stopped the work on A31, we decided that A33 is promising device as it have Mali video and there is chance to have open source drivers and Linux support with hardware acceleration.
A33-OLinuXino is OSHW project and you can see the preliminary files at GitHub.
With size of 70×76 mm it’s small SOM like board, you can see the component arrangement above:
There are two 40 pin 0.1″ connectors: upped for LCD connector, lower for GPIOs, I2C, SPI, etc
A33-OLinuXino have PMU AXP223, A33 Quad core Cortex A7 running at 1.5Ghz, 4/8GB NAND Flash, 1GB RAM
On the left side you can see USB-OTG, LiPo battery connector, debug UART, button, micro SD card on the bottom
On the right side there are Audio IN and OUT connectors and flat cable connector with MIPI and CSI signals.
We still have no idea what it will cost when released as we don’t know how many layers will be the PCB, but we guess it will be in the LIME range i.e. about EUR 30

Why not KiCAD?!
May 18, 2015 @ 18:31:55
so far we use KiCAD for smaller boards and we found/reported lot of bugs to authors 🙂 still don’t dare to use KiCAD for this kind of complexity, we work with the extreme upstream version of KiCAD and it happens from time to time the new version to mess with libraries, reverse parts footprints etc, if you do not check carefully everything after the next upgrade you may shoot yourself in the foot. We are waiting kiCAD team to release stable release in June/July and then will reconsider
Jul 23, 2015 @ 11:28:54
Have you heard any news regarding KiCad team and the release of stable versions this summer?
May 18, 2015 @ 18:35:35
Hi, can you give some more details on the board – what kind of Linux will be supported – some Linaro build or an official distro? Any idea whether it will support stuff such as OpenGLES 2.0?
And I know it’s too early, but any chance of giving a (rough) estimate on when it will be available to buy?
May 18, 2015 @ 18:41:14
what distribution – most probably Debian as all our other boards, about opengles 2.0 have no idea, when Linux-Sunxi implement it, what we got from Allwinner is Android which compiles fine and we will modify it to support board features at beginning until there is proper Linux support
May 18, 2015 @ 18:43:15
Ok, thanks!
May 18, 2015 @ 20:41:17
How about Ampak wifi modules?
Of if you are more ambitious, reuse the iPhone4S wifi/BT module of which there are millions of in Shenzhen with no use for them.
May 19, 2015 @ 02:53:02
Why not just a ESP8266 connected somehow – simple, cheap and tested. I am not sure how the communication between the A33 and the ESP is gonna go, as it is takes textual AT commands as far as I know.
May 18, 2015 @ 20:45:55
Looks quite interesting. Too bad Ethernet will only be possible using e.g. USB
I’m still looking for a decent board that has Line-In and Ethernet. Olinuxino A10s fit the bill but is discontinued.
Alternatively a board with Ethernet and I²S that doesn’t need SMD rework to access the I²S.
May 18, 2015 @ 23:21:55
“Alternatively a board with Ethernet and I²S that doesn’t need SMD rework to access the I²S.” Cubietruck is the best option I know of.
May 19, 2015 @ 09:38:56
Last time I checked the recent Cubietruck required SMD rework to make I²S available. Page 11 of the v1.0 schematics lists the I2S pins as “NC” and requiring repositioning a SMD 0-Ohm “resistor” (R174ff).
May 19, 2015 @ 14:13:00
Yes, I forgot I moved a couple of resistors on the Cubietruck. It was no big deal. It took about five minutes. If you get your board from iotllc.com I think George will move them for you if you ask.
May 19, 2015 @ 00:34:05
Correct me if I am wrong, but I believe many OlinuXinos have line in – just not broken out on a connector but on pin instead.
P.s. Actually the board in question has mic in and headphone out on connectors which makes sense for end users – the line in/out are also on pins here – check the schematic in github 😉
May 19, 2015 @ 10:19:44
Yes, pin headers are fine too. This board doesn’t have Ethernet, because the SoC doesn’t even offer it, so while it’s nice and welcome, it doesn’t fit my use case.
I’ve looked up the other schematics and the LIME(2)’s seem to have Line-in on GPIO-4. I’ll have to get one to evaluate the audio quality.
On a tangent: I²S on those doesn’t seem to be even routed anywhere. Not complaining, it’s a reasonable design choice, given that Out/Mic/Line are available.
May 18, 2015 @ 20:53:41
One thing: unless you intend to make just another Android-SBC forget NAND-flash. Replace the NAND with a Micro-SD socket, please! Best on all future boards.
Using NAND under Linux is a real p.i.t.a. Support for MLC-NAND consist of rudimentary binary blobs for Android. That’s all. Mainline kernel NAND support is for SLC and not suited for MLC. On top of that, NAND is slow. µSD on the the other hand would be cheaper (for you), faster and trivial to use. I hinged type socket somewhere on the board would be good enough – no need for the clicky type on the board edge.
Another alternative would be eMMC chips but I think they are rather expensive.
May 18, 2015 @ 22:37:42
Bottom left is power, right? 5V?
May 19, 2015 @ 02:50:39
Hmm, A33 should support https://en.wikipedia.org/wiki/OpenMAX
But I dont’t exactly understand if this means easy and open video acceleration?
May 19, 2015 @ 10:42:38
No HDMI/VGA?
No Ethernet?
One USB port only?
No power jack?
AllWinner H3 seems like a much better choice for a dev board.
May 21, 2015 @ 09:41:06
Just checked price with my partner in China whom interested.
A33 – $3.35 (1000pcs)
AXP223 – $0.38 (1000pcs)
May 21, 2015 @ 10:00:19
did you ever run mass production with chips from this supplier? what guarantee your partner gives for the chips? these prices are below Allwinner sell prices, I guess some silicon scrap out of parameters when QA tested or pulls from old equipment?
May 25, 2015 @ 21:31:27
I agreed, It would be silicon scrap and I didn’t work with this supplier in mass production. I worked with them to get a few samples of Raspberry PI chip. It was funny. Some Chinese Girl pinged me on Skype and offered BCM2835 🙂 I tried to get it officially directly from Broadcom here in US. They are declined my requests and during face to face conversation seriously told me that sale agreement to get BCM2835 should be at least $1 million. Then I got samples from Chinese Girl + mobile memory chip on top. Reflow these chips on my original Raspberry PI and get it worked 🙂 But I didn’t risk to continue to build my own Raspberry PI clone, intention was… Long story short…
May 25, 2015 @ 21:36:30
BTW, I can’t find official Allwinner distributors. Any info? I did requests on their web-site, but no response. I’m interested in volume with QA warranty…
May 21, 2015 @ 15:03:58
Mike – are you sure that is not a price for the A23? It is at least $1 below the other distributor’s A33 price. Y26-Y30 is more common.
May 25, 2015 @ 21:39:29
Here is Chinese Girl prices:
A33 Allwinner 1000pcs TFBGA-2 $3.35 /pcs
AXP223 X-POWER 1000pcs QFN $0.38 /pcs
A10 Allwinner 1000pcs TFBGA-2 $3.73 /pcs
AXP209 X-POWER 1000pcs QFN $0.15 /pcs
less than 500pcs

May 25, 2015 @ 21:43:28
Funny comments, especially about warranty…
lead time :1-2days,warranty time:30 days.
May 25, 2015 @ 22:07:46
LOL do they stop working after 30 days 😀
the $0.15 for AXP209 is also unbelievable for new chips
May 25, 2015 @ 21:49:13
Those prices are messed up. A10 is available from many sources for under $3.00. A10 should be cheaper than A33.

I have 2000 pcs MAX232N for sale $0.20/each I got them from Alibaba supplier few years ago at very good price and they work fine, just have 0.3A power consumption and can be used also for room heating 🙂
May 21, 2015 @ 23:54:00
0.3A on what voltage? If I can make a cheap and powerful radiator I may be interested 😀
You are joking but people are already making money out of heating with servers:
http://www.treehugger.com/clean-technology/nerdalize-warming-homes-heat-cloud-servers.html
Maybe you should think of a more powerful (thermal wise) OlinuXino 😀
May 22, 2015 @ 12:18:29
MAX232N works on 5V x 0.3A = 1.5W consumption good enough to heat your fingers during cold winter days 😀
Jun 10, 2015 @ 08:20:51
very thanks for this new A33 Allwinner product
i want to know that how day complete this board and we can buy it
Aug 23, 2015 @ 12:28:51
i waiting for your replay (OLIMEX Ltd)?
how day this product to be complete?
i want to buy it!!
so thanks
Aug 24, 2015 @ 19:12:24
Hardware seems to be complete, no much update on the software side:
