content: i opted for open source board from itead. i got 2 boards as promised, one from itead craft and one is this.what a load of crap. it has OSHW logo but nothing else. how do i figure this one out?ps: it looks like power app board, some power transistors and few peculiar thick ICs. but thats all i can tell

content: You pay an extraten centsand you take the chance that you'll get something useful. If not, no big deal.Itwould be niceif people would put a link to some documentation but not everybody gets that.

content: Quote from: Jon Chandler on November 08, 2012, 09:24:20 pmits actually free. my point was, if people want to declare their design OSHW, furthermore bother to put the logo on it...Quote from: Jon Chandler on November 08, 2012, 09:24:20 pmyeah that! the point. so we can easily search what kind of OSHW it is. should it be in the OSHW regulation? nobody's going to enforce it anywaybut at least as a recommendation?

content: Maybe it was not known at the time that the board was laid out that it would be shipped to random people without any documentation? I don't see this as a typical distribution model for an open hardware design. I guess some sort of model name in the silkscreen might be useful, but calling a product crap because it was not designed for the PCB pool does not seem fair.

content: i put the question mark in the title so its an open discussion and i'm not so sure. your argument is valid for me that it was not known to be given/distributed for free from another party.

content: You already know what it is, but the smal modules and the 1A 1B 2A 2B smell like stepper motor controllers, then there is the Arduino header pattern, so it must be a shield, and arduinos plus lots of steppers it can only be a 3d printer.

content: QuoteHmm. That's a good point to keep in mind. I suspect that not everyone who tags their board as "open source" is crazy about providing "support" to the random people who might have gotten one through Itead's service, though. That a board is "open source" doesn't really imply that it's a "product" somewhere.

content: Itead's idea of a low cost board exchange is nice, it is the random assignment/fulfilment that is wasteful and inefficient. If they had an inventory of whats available for grabs and let you choose I would go for it, but maintaining and displaying that inventory is work. As it now stands I looked at that option and said "I don't want to be surprised" and just ignore it.
