View Full Version : About to give up on the Raspberry Pi

01-13-2013, 02:41 PM
I've been trying to make my quad walk on its own using a Raspberry Pi for control, and a ATmega32u4 for the low-level servo control, talking USB.
The ATmega32u4 and the control program works great on regular Intel hardware with Linux. However, on the RPi, I've been getting strange, intermittent cases of USB just dropping off the Earth.
Now, I've found a thread on the RPi forums about the RPi having USB hardware bugs that the software tries to work around, but may not be able to do. That's... a shame! It's a nice, small form factor with reasonable power. The next "step up" would be a BeagleBone, with approximately the same amount of power but a higher price point, and unknown USB capabilities.

Then I found this:

1 (http://www.zotacusa.com/zbox-nano-xs-ad11-plus.html)05x105x45 cm, full x86 compatibility (AMD,) solid chipset. I'm in love!

I do believe that is what the NimbRo-OP uses with its 4S battery instead of a fit-pc2i-sbc. The E-350 in my pc works quite nicely and the slower C-60 in my netbook can almost play 1080p movies smoothly (have not tried the restricted drivers). Unfortunately, ATI GPU processing is not as widely supported/popular as NVIDIA CUDA.

edit: bleh, the fglrx drivers suck something awful.

The gpu would actually go unused. Unless I use it for development, too!

I've actually been looking at these as well. The AMD-based Zotacs look to be quite a bit less power hungry and expensive than the Intel NUC. One thing to keep in mind is that there are actually 3-generations available, the AD10, AD11, AD12. The AD11 for whatever reason uses a USB-based Wifi (unlike the mini-PCIe used in the 10/12 generation).

Ad12? Didn't see that one.
Is it smaller than the 11?

No, it's bigger. So ad11 it is! And it looks like you could pull the circuit board out if you wanted a custom enclosure.
