The cheapest computers available
On its release in 2012, the $35 Raspberry Pi showed just how much computer you could get for a bargain-basement price.
But the cost of single-board computers has just kept dropping, with the Raspberry Pi Foundation releasing the tiny Pi Zero for just $5.
Today the Zero is one of several computers with a single-digit price tag, and if you're looking for a cheap as chips board you're spoiled for choice.
These are the single-board computers that you can pick up for less than a price of the $35 Pi 3.
One thing to bear in mind is that the cheapest offerings lack many of the features of the Raspberry Pi 3 Model B, and have more in common with the $5/$10 Raspberry Pi Zero.
Even the more expensive boards are at somewhat of a disadvantage compared to the Pi range, lacking their breadth of stable software, tutorials and community support.
nanoPis are ~ 10E$ cheaper than RPi; however, their connectors are not through (seems to make the price difference) , are not as easy to find and they are somewhat -ca 30% slower-
Simplify Industrial-Grade Linux Designs with SAMA5D2 MPU-Based System On Module (SOM)
Power management, non-volatile boot memory, Ethernet PHY and high-speed DDR memory are integrated on a small, single-sided PCB enabling smaller, efficient designs
Customers can solder the SOM to their board and take it to production, or it can be used as a reference design along with the free schematics, design and Gerber files and complete bill of materials which are available online.
...
The ATSAMA5D27-SOM1 is available now for $39.00 each in 100 unit quantities.
The SAMA5DS27 SOM is based on the ultra-low-power, 500-MHz SAMA5D27 that contains a 32-bit ARM Cortex-A5 processor. The SOM adds 128 MB of DDR2 DRAM and 8 MB of QSPI flash memory. ...
This [PMIC] allows it to operate with a single 3.3-V power supply.
...
It [SAMA5D27] can handle on-the-fly encryption and decryption from DDR memory. The system also has either tamper detect pins or secure key storage, and ...
...
By the way, many developers will appreciate that the SOM [103 IO pins] can be soldered by hand. This is handy when building prototypes.
...
... [EVB] and an SD card slot that can handle memory or peripherals such as wireless interfaces.

Microchip's Linux4SAM.org site provides examples, and Yocto and Buildroot support for all Microchip SAM platforms. Security support is available through the Sequitur Labs IoT Security Suite.
I actually do not have much love for them because of the software blobs needed for the broadcom chip.
broadcom is not a hacker or Open Source friendly company.
They just happenened to have some obsolete chips left over when the first raspi came out.
I believe it was ARM5 or ARM6 and it was on the verge of bein kicked out of Debian because of it's obsolence.
That damn Raspi kept developers backporting stuff for years.
But thanks for bumping this.
Just yesterday I found a link to a
2018-02-xx Comparison of 103 small Linux boards.
All these boards seem to have been vetted for capability, availabilty, and up to date ness.
Because it is such a nice overview I wanted to post it here, but I could not find this thread and was a bit in a doubt wether I wanted to resurrect this thread for this.
I do not often post links to commercial companies. It always leaves a nagging feeling I should be payed by them for the advertizement...
But I do mention Olimex for a few reasons:
1). Olimex is a pretty hacker / Open Source friendly company.
2). Olimex has the complete designs of their boards (Schematic & PCB) on Github.
3). Olimex sells the bare Allwinner chips in low quantities for reasonable prices.
2) and 3) combined with the other documentation will give you a decent head start if you want to roll your own board.
Edit: This Fosdem talk might also be sligtly relevant.
It's about "Common windowing and Video Acceleration" to make software more easily portable between the myriad of small Linux boards.
The combination of binary blobs for video drivers and the DRM stuff which are all implemented differently for different manufacturers makes it pretty hard to write some good code with the performance needed for Video Decoding on these small boards.
So what? For the intended audience (and the multitudes of other users) it serves its purpose fine.
I know, and It's good I guess. It is just that I have sensitive feelings about the philosophy behind the open source movement. I am really convinced that this can help in making this a better world. If you look at projects like KiCad, FreeCad, GCC itself, and thousands of other linux (and other) open source projects, where people give ther work away in Freedom to give something back for the enormous amount of knowledge they get for free on the internet. Look at the enourmous amount of code shared on sites like github...
And it does matter "For the intended audience". It is good if the "intended audience" does not only get Cheap Fun Computers to play with Linux (or whatever), but they at the same time get some more insight in the philosopy behind the Open Source movement.
On the other side you have the "commercial companies". They are not only keeping their "intellectual property" a secret (I can (sort of) live with that) but they are also actively fighting and trying to destroy each other, and half the world with that. Look at the "FUD" campain of a certain unspeakable company. A long time ago I was bitten by the same Shit Factory. I was trying to graduate from school and it took a week out of the time I had for writing one of my first serious pieces of software just because I had to change a ftp server program in a bunch of strange ways to make it compatible with that same companies idea of a "malformed" ftp protocol. Yugh. How about a C compiler that generates abbysmal code if it does not find the text string "genuie intel" in some corner of the processor. Yuch! Printers and scanners that stop working after a few years because their "drivers are outdated". One of the biggest leaps in society will be that there will come a time that behaviour like that will simply not be accepted anymore. But this will probably take generations to achieve such a culture shift. But it's hard to predict in this time of exponential everything.
About the "ARM11" architecture. Yeah that was it. On the other hand. It won't surprise me if some of these old architectures will make a comeback once the patents have expired.
SparkFun Raspberry Pi Zero W Basic Kit comes with everything needed to get started with the Pi Zero W. The Raspberry Pi Zero W is smaller than previous Pis at only 65x30mm with wireless LAN and Bluetooth®. The Pi Zero W is ideal for embedded Internet of Things (IoT) projects and has been designed to be as flexible and compact as possible. The board features mini connectors and an unpopulated 40-pin GPIO. Each kit comes with a Raspberry Pi Zero W with a fully programmed NOOBS card, Mini HDMI and USB OTG cables, and a high-quality wall adapter.

TopCertainly not the hardware itself - but the "community" that has built up around it.
So what?
For the intended audience (and the multitudes of other users) it serves its purpose fine.
You mean ARMv6 - commonly known as "ARM11"

TopThey initially provided a fairly reasonable schematic for the first boards - certainly enough to use the boards.
But the detail released for the later boards is pathetic - useless if you have any question of what happens behind any of the IO pins.
