Broadcom is still Broadcom.

It doesn't look like BCM is intending to release any more datasheets/programming information either, which is not surprising. There will probably never be any detailed information released, officially or otherwise, on any BCM SoCs, even after they're long EOL'd. As far as openness is concerned the RPi is basically a smartphone/tablet SoC devboard, with most of the hardware proprietary - while its Chinese competitors…

Allwinner will give you their datasheets if you email them. Mediatek not so much (& no experience with Rockchip).

Any news if the Raspbery Pi 2 will have USB 3.0 ports? That seems to be a good selling point for the Odroid XU3 currently... USB 3.0 ports would mean better performance as NAS or multimedia recording solution, as well as alleviating some of the current troubles with usb performance.

No chance.

Why are they required to release those datasheets?

They're not, but it's been common practice in their industry for decades, and it's generally seen as beneficial to OEMs and users to have access to datasheets before purchase. This is why it's also commonplace for most chip manufacturers to offer free samples, even of chips upwards of $20 list price. Most of them even publish enough information to develop hardware and software to interact with these chips even withou…

I can see how you might think that seeing as how a lot of manufacturers in the low cost and hobby markets are quite liberal with their datasheets . but it is not uncommon in regards to the higher end soc companies like marvel,qualcom or in this case broadcom.

Why would anyone buy this over the much more powerful ARMv7 odroid-C1 for $35 that has been out for months now?

The Raspberry Pi is a platform optimized for and bundled with its community. The Raspberry Foundation can produce/license any conceivable number of these devices at the same price point. The difference of for example $35 vs $70 doesn't matter very much for individual buyers. It does matter when dealing with educational budgets and a desire for predictable spending. Even when a school/hobbyist course requires students to buy their own devices, even $5 differences can be a big deal.

The fixed price, high bulk, cooperation with education initiatives and governments, all translates to a relatively homogeneous, unfragmented "fleet" of devices, which just isn't the norm in small computers.

Beagle Bone, the Odroid series, and several other products are technically superior in most ways. But they don't have a comparable community size, and aren't focused on the educational sector as much. In some ways, these models attach to the Raspberry Pi community.

Awesome!! I just wish they would release one with onboard Wifi instead of ethernet. I have no statistics to back this up, but I'm pretty sure that USB Wifi adapters would be the most common accessory.

It's probably the economics of FCC/CE testing vs utility. The testing for unintentional radiators is onerous enough. If you add an intentional radiator, you trigger a whole lot more tests and a whole more cost.

How does this compare with the ODROID-C1? http://www.hardkernel.com/main/products/prdt_info.php?g_code...

For teachers one big issue is that you don't know if you can buy 100% compatible devices in a year's time in comparable conditions (price, bulk, availability etc). With Raspberry Pi you know you can.

That was pretty much my feel as well. So much for "now the CPU's fast"... yeah nope.

I thought the issue was mostly about lack of support?

meh, it'd be nice if it was more open from the CPU point of view but it kinda works out, plus "there's always hope". Can't make up for the lack of instructions and power.

Heck, both of them reasons while I like intel chips afterall. Their newest ones are pretty sexy too. I'm hoping sexy boards of similar form factor, and... oh yeah price.. err. yeah not going to happen :(

So in the meantime armv7+ boards are pretty decent (with similar random support, which, also mostly works out)

What's the same: - Same form factor as the model B+ (your enclosures and daughter boards should still fit). - Same full size HDMI port - Same 10/100 Ethernet port - Same CSI camera port and DSI display ports - Same micro USB power supply connection What has changed: - A new turbocharged Broadcom BCM2836 900MHz quad-core system-on-chip with performance at least 6x that of the B+. - 1GB of RAM Source: http://raspberry.…
