64 Hacker Friendly Single Board Computers (linuxgizmos.com)

An anonymous reader writes: This year, we've seen some incredible price/performance breakthroughs in low-cost single board computers. LinuxGizmos has put together a compilation of 64 low-cost, hacker friendly SBCs that are all available in models that cost less than $200, with many well below $100, including Shenzhen Xunlong's $15 quad-core Orange Pi PC, Next Thing's $9 to $24 Chip, and the $5-and-up Raspberry Pi Zero. Processors range from low-end 32-bit single core ARM chips, to 64-bit ARM, x86, and MIPS parts, and with clock rates from 300MHz to 2GHz. This year even saw the arrival of low-cost SBCs based on octa-core processors, such as the $88 Banana Pi M3.

The usual thing is to run Debian on them, but you can also run Arch and maybe Gentoo. They are surprisingly solid little pieces of hardware and I get tolerable throughput to Ye Olde MyBook 3GB from my Win7 PC through my cheapass Dlink GigE switch, somewhere 20-25MB/sec. I have only used the SATA on occasion and never with a device even as fast as that, only with a laptop disk. Still you can not beat it for SATA on an ARM SBC; not only is it cheap, but it's a professional product with a quality case, and a decent ethernet cable and wall wart.

      Right now I am using a Fire TV stick in the living room because the MK908 never became convenient enough to use. I may try again with PineA64+, assuming that even pans out. But my Pogoplug faithfully shovels bytes out to that, running Kodi.

      There are many other revisions of the pogoplug hardware; I recommend none of them. I never had much luck with them being stable. I have also never used any other Sheevaplug-based or -descended hardware, so I can't speak to any of those, just to the pogoplugs. I also have a dockstar, which is just a tiny pogoplug, and it was never very reliable either. The V4 pogoplug on its original wall wart has been great. You will need at least a 2GB SD card and I suggest at least 4GB (for elbow room) for your Debian volume. I am using ext3 for boot and ext4 for root, with great success. I'm running both samba and nfs, and I can use both at once and nothing craters, which is pretty much the total use case for the device.

      Many SBCs have USB power, but realize that's just a 5VDC connection with a funny plug which takes up space in your build. If you're lucky they also take power via a header pin, like the Pi. What you really want IMO is power over ethernet, which virtually none of them support. You would have to add a power supply before the device on some of the ethernet wires. However, that's fairly well irrelevant in the case of a storage server, where you'll need power for the disk anyway.

Maybe even an SSD as I seem to recall that those were less power. Something that's not just a "dumb" disk but also has a full blown NAS OS on it - like FreeNAS or similar. Basically, it'd get power from USB (and probably allow data transfer) but, while plugged in, others could connect to it wirelessly and push and pull stuff to it or even have scheduled backups and the likes.

      Then, if wanted, I could toss it in my bag and lug it with me and not have to bring a power supply. It'd be nice for times like now, when I'm out on wanderlust, and there are multiple devices that should be backed up - as well as having access to other files.

      The way it normally works on the R-Pi is to use two USB cables, one from the device to the hub, and one from the hub to the device. You can also just buy Mini- or Micro-USB connectors as appropriate and then solder power wires to them for those devices which lack header connectors for power, they are cheap on eBay. It is possible to hack a hub to feed power back to the Pi over the USB connection to the hub (normally it goes the other way, right?) and hack Pi to get that power from the hub, but then you'll have some weird incompatible peripherals. It would have been nice if the power supply on USB could have gone in either direction, but alas, no.

      If you're reading analog sensors over long distances, you're better off running the digital lines for the long distances, and reading the analog sensor close to the actual sensor itself. If you're reading them over short distances, then as you say, you want the A/D onboard. Most cellphones have little need for A/D outside of the audio hardware, though; these days, instead of having to read a PWM signal directly from a sensor, you just get everything as I2C or whatever. So the cheap SoCs only have digital I/O, audio aside. That's why Pi doesn't have it; it would just cost money, and a lot of people won't need it at all so why spend it? You can get A/D boards cheap, so it's not a very arduous requirement.
