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

The link at the bottom goes to https://beagleboard.org/wireless which isn't working for me, but https://beagleboard.org/black-wireless works. Mouser lists the price as $68.75 and element14 as $99.25; neither has any stock yet. There are hardware design source files on https://github.com/beagleboard/beaglebone-black-wireless , including a PDF schematic: https://github.com/beagleboard/beaglebone-black-wireless/raw... w…

Can it be that those prices are imaginary until there's stock? It seems like a nice board (I have a old BBB, with ethernet, and it's solid), but the CHIP [1] gets you wifi and BT for $9...

As a side note, "DDR3 8Gb 512M*16 1600 MHZ" is now on DRAMeXchange (you have to login to see it). It is hovering around five dollars per chip. I think the BeagleBone Black is one of the embedded systems where it is commonly used.

anyone know of any good resources, tutorials, books, etc. for putting the PRUs to good use? those seem to be the defining feature that separates the BBB from the other SBCs.

Earlier quoted context omitted.

You may be thinking of the ODROID-C2. http://www.hardkernel.com/main/products/prdt_info.php

Thank you. That looks like one of the ones, perhaps the only one, that I recall. Gigabit Ethernet, even. Do wish the USB could be >= 3, but for $40, I'm not going to complain. Mali™-450 GPU (3 Pixel-processors + 2 Vertex shader processors) I'm thinking this implies a binary blob?

This looks like the source for a Linux Mali-400/450 driver: http://malideveloper.arm.com/?modals=mali-400450-linux-kerne...

I haven't really examined it, though. Maybe there's also a binary blob loaded into the GPU itself or something (the Raspberry Pi does that, for example).

Hopefully they don't need to use a closed-source blob for the C2.

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've been running a tor relay on the original beaglebone black for a couple years now and have been very satisfied. Would have LOVED the wifi model back then.

Honestly, with it supporting only 2.4 ghz, its uses are limited.

What's wrong with 2.4Ghz?

The BeagleBone was great when it first came out. Then the Raspberry Pi came out, and has a bigger community, higher performance, and lower price. Compared to the RPi 3, the BBBW seems like ... too little, too late?

Does RPi have PRU co-processors?

No, but the GPU actually contains a non-ARM general-purpose processor. I think we're in the very early days of knowing how to program for it.

No, you can't for example control RGBW one-wire LED strings with a Raspi. On the BBB thanks to the PRU you can do so with 0% CPU load.
