What's unclear is how the BeagleBone Black Wireless compares to the SeeedStudio BeagleBone Green Wireless: https://beagleboard.org/blog/2016-07-07-seeedstudio-beaglebo...

It looks like the Green wireless has more USB ports, but aside from that, I'm not sure why you'd choose the BBB Wireless vs BBG Wireless?

OT, sort of, but a while back I saw one of these... "Pi-like" boards that had two Ethernet ports. It also had significantly more horsepower. I'm wondering what might be recommended choices at this point for someone looking for an inexpensive, wired MITM / Firewall platform. P.S. It would be great if it also had decent on-board wireless for e.g. making a portable hardware firewall device.

There's this http://pcengines.ch/apu2.htm which runs FreeBSD quite well and has gigabit/etc plus the ability to add wireless

Unfortunately its power usage is crazy bad. It draws about 7W when idle. Devices like the BeagleBone, Pi or even most consumer-grade wifi routers draw a fraction of that.

The board SoC quality is very good. However, it can not compete with e.g. the CHIP SoC board [1], which costs just 9 USD + shipping with similar specs (I have two CHIP running 24/7 without any additional cooling, running rock solid -even in summer, at 35-40º C indoor-). The only thing that would make me consider buying the BeagleBone Black Wireless is the two built-in microcontrollers ("PRU" processors [2]), for real…

Unfortunately even though I 'bought' a CHIP some 6 months ago I have yet to actually receive it. It's very easy to source a BBB. Hopefully in the future thy become more available. Though I fear that will come with an increase in price.

I am also waiting for a couple of ones since a couple of months ago, in case someone needs another data point.

But the CHIP uses an Allwinner CPU, and for those of us who like to support manufacturers that actually play nice with the open source community: the CHIP is a no-go. The specific CPU in the CHIP appears to have mainline support, so it's less terrible than things like the "Banana Pi M2+" ( http://linux-sunxi.org/Sinovoip_Banana_Pi_M2%2B ), but I like to support CPU manufacturers who aren't Allwinner.

While the motives are nice, there is no way I am willing to reward a company like the one who makes the beaglebone black that effectively scams its customers by charging such a huge amount relative to other products.

Why do you consider charging a higher price as "scamming"? For example a SABRE Lite board is much more expensive and has a weaker processor than, say, a Raspberry Pi 3. Nevertheless it has advantages, for example it is much more open than an RPi3 and thus it is much easier to do bare-metal development on it, which is a reason why for example the seL4 developers use it as (one of the) build target(s) (cf. https://wiki.sel4.systems/FrequentlyAskedQuestions#On_what_h...)?

I think their fulfillment process has been hit-or-miss. I ordered a CHIP in December 2015, received it in January 2016. However, my VGA adapter didn't arrive until late June. Part of the problem is their confusing order process; peripherals like the VGA adapter were being advertised as shipping in February/March, which was when I expected mine, but when I inquired about it via email I was told they had not even started physically building them yet, and I'd get mine "some time this year".

Still, for $20 total outlay I have something that is between the Raspberry Pi B+ and 2 in performance, with arguably better expansion (if you value GPIO over USB), and a few nice extras like a power/reset button and built in support for LiPo batteries. The downside is that it's based on an Allwinner chip, and that company is known for being open-source hostile. Supposedly they are trying to improve, but it does limit the range of operating systems available for the device.

The level of ignorance in that statement is stunning. First, the Bill of Materials for the BeagleBone is publicly available. I'm quite sure the BeagleBone guys would welcome your help in finding parts that are significantly cheaper than what they have now. Second, the BeagleBone comes with a bunch of very standard connectors that are optional or hobbyist installs on a lot of the other boards. Ethernet jack, 2 usb por…

> RPi adopted these things later and, funnily enough, needed to increase their price when they did so.

This is my only nitpick with your post. While the Pi was in development, yes it was advertised as a "$25 computer", and once they finalized the design of the B version it ended up at $35. However, its price has not increased one penny since release, despite several revisions and huge leaps in performance and capability. Today we have the RPi 3, a quad core 64 bit computer that sells for the same price as the original single core, outdated-on-release board from 2012. If anything, that means the price has technically gone down, since you're getting so much more for the same amount.

Beagleboard's come with PRUs, for which, if you need a lot of very fast GPIO, there's no substitute. I've driven 9000 LEDs at 100fps with Octoscroller

Just use one of the for cores on a rpi2 locked to GPIO duty and you can run them as fast as you want...

I've heard this mentioned before in the passing. How does one actually do this.
