I have a few chips too. Running one as a jukebox. Not sure what to do with the others yet. What do you use yours for?

Funny story (I think): I happened to have brought a C.H.I.P. when I went back to europe for vacation. My father proudly showed me his new solar array and the log he had collected manually. After a bit of googling, sourcing a USB-serial adapter locally, and a few long nights I had the CHIP collecting this from the Growatt 3000's serial port and uploading it to pvoutput.org. It's still running 24/7. EDIT: I have too ma…

I'm not trying to be a jerk, I am just curious if I missed something. Where is the humor?

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?

They have different features. RPi still doesn't have any support for analog. The BeagleBone has had an ADC since the beginning. If you are using them for anything more than a basic computer these little things matter.

The BeagleBone Black has better Linux support out of the box, doesn't require non-free firmware to boot, and is itself an Open Source Hardware design.

It's also massively more capable on the GPIO front. I used mine for a project with a lot of analog input that a Pi would never have worked for.

What's wrong with 2.4Ghz?

5GHz performance is vastly better in urban areas. There are 26 networks visible from my apartment (in a small 2-story apartment building), and the 2.4GHz WiFi spectrum effectively has only 3 channels (due to substantial overlap, only channels 1, 6, and 11 are normally used). So you're sharing a lot of bandwidth with your neighbors. 5GHz has much better spacing (so less interference) and more total bandwidth.

5GHz also attenuates significantly through walls, so even if your neighbour is on the same channel you won't be getting as much interference.

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?

Probably the HDMI port.

This is the perfect example of true Open Source Hardware. None of the other boards similarly spec'd development boards have been spinned into so many variants. Not to mention real world consumer products that are based off the Beaglebone Black schematic.

I had a student try to do an independent study research project using the BBB a couple of years ago. The experience wasn't good. We had a lot of trouble getting the thing to run with anything except the one kernel version that it came with. Porting over features from kernel modules done on earlier minor versions was a huge pain and not at all straightforward.

This has definitely changed. I'm using the current mainline kernel and it includes proper configs for the BBB. Works pretty much hassle-free.

Yeah this changed a lot in the last 12 months.

Problem was to support capes (addon boards) especially dynamically and at runtime wasn't really supported in mainline. They had special cape manager patches to do it but it wasn't a good solution for upstream.

3 years later or so we finally have good overlay support for this in a mainline happy and now merged way. They paid to have this work done which is great, though sadly took a long time.

I forget the guys name that did it but he is clearly a champion of patience.

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.

I had this one bookmarked from awhile ago:

The BeagleBone does power management which the RPI doesn't. It's unfortunate that they didn't take this revision opportunity to boost the RAM and switch to USB3. IMHO.

> It's unfortunate that they didn't take this revision opportunity to boost the RAM and switch to USB3. IMHO. Well, the RAM on the Bone is DDR3 while the RAM on the RPi3 is DDR2. I'll generally take the extra performance over an extra 512MB. With respect to USB3, USB Type-C connectors are WAY more expensive than micro-B. We're talking like more than a dollar vs less than 10 cents. And USB Type-C cables are way more e…
