Raspberry Pi Goes On Sale In US, Sells Out
hypnosec writes "Easter has brought some good news for Raspberry Pi fans in the US as the $25 Model A of the credit card sized computer is now available in the United States. Texas based Allied Electronics is the first local retailer selling the Raspberry Pi in the U.S. and has been selling the Pi through its online store. (There were companies selling the Raspberry Pi over eBay to U.S. users for a higher price tag earlier.) The Model A has sold out completely and as of this writing there is zero availability."
They have Model B, but no Model A. I want a Model A because I plan to use the device as an embedded controller and I will likely code my own assembly or C code, no need for a linux stack. So, where can I get a $25 Model A in the USA?
I already have a few Model B's. I will develop on a Model B, because the ram makes a performance difference. My projects seem to either need more than 2 USB ports anyway, so the built in 2 port USB hub on the B doesn't help. I usually have an external hub. And most things I do are wireless, so the built in ethernet isn't useful. So why pay the extra 3.5 watts?
I am playing with a pcDuino from Gadget Factory, and they are also available from Sparkfun dealers.
At US$59 it is a bit more expensive, but does have a few advantages
- Onboard 2GB of Flash to hold an OS - no SD card needed!
- Decent Power supply system for USB ports
- 1GHz A8 CPU - More than 2x as fast
- 1GB RAM
- Mali 400 graphics accelerator
- Android image available
- No need for an I/O expander for hardware hacking
Once you take off the cost of a powered USB hub and an SD card for the making the Pi usable I think it is price neutral between the two.
I've been using Android on it to play back 1080p files (at 720p) without a problem, and play Angry Birds Star Wars... can't do that on a Pi.
The Australian company Miniand make similar boards, some with cases and so on. Their Cubieboard even has SATA header on it, and I've got one with a 2.5" 120GB disk hanging off it...
As a package, the Pi is already obsolete and outclassed. Where it does have an advantage is it's very easy to flash (just stick an SD in it), has a large and coherent support base, and has some connectors for hooking it up to other things.
