I assembled my USB Boarduino last night. Nothing too tricky. In fact, I found it much easier to refer just the parts list instead of the step-by-step instructions and just to use a little common sense on the order to put things on.
in lieu of assembly instructions, the parts list will clarify which components go where. the only part i missed was the jumper, which is labeled 'PWR' on the pcb just behind the usb connector. the photo can be referred to in a pinch.
yes, all the info one needs is there, assuming an intermediate level of experience or better. but there are a few head-scratchers if you try to put it together w/o using the parts list or photo.
As the poster above said, the power jumper may not be obvious. I'm fairly technically inclined and I missed it. I just assumed it was designed in for some future use. Of course, when my board wouldn't light up like everyone else's I became suspicious. Gotta connect it.
For noob builders, your best bet is to use the parts list and extrapolate where they all go. If you go by the DC tutorial, note that d1 was eliminated on the usb version so d2 becomes d1 and d3 becomes d2. Also note that the six pin piece that goes by the reset button has the long pins up so you can jumper them. (still havent figured out what to use those for tho)
Seems like a little photo copy of a populated board and a few relevant notes would be included but I guess that would make it too easy... Just pretend you went to banned and enjoy puzzles. Dont stress!
I just finished (finally) soldering mine up, and notice there are some unpopulated holes. One is right by the 4 in the C4 silk screen, and there are 3 under the large socket. Did I miss something? I sure hope not...
I'm not familiar with the "USB" version of the Boarduino, but it sounds like those are just vias: pass-throughs to electrically connect a circuit trace on the top side to one on the bottom side. Are they a wee bit smaller than the other (soldered) holes?
