Anyone interested in an eagle version of the Netduino files?
I've seen a couple of threads about the board and schematic files and people wanting them in Eagle, is anyone interested? I'll port them over if there is enough interest - i have an Eagle Pro license so the 4 layer restriction is no problem to me.
I have a feeling i'd have to do a redraw from scratch, so the routing will be different however components should mostly be in the same place (all the important stuff anyway) - it would be enough for using to generate your own netduino based devices in any case.

I presume people wants the Eagle file so they can make their own boards.
Are there a non surface mount versions of the chips used by the Netduino and Netduino Plus? I would love to build my own Netduino board, but I do not have the robotic nerves of steel to solder those surface mount components.
Hari, with 100 pins there is no way you'd get that in anything other than LQFP/TFBGA/LQFN packages. Those IC's are really easy to hand solder once you know a few tricks. I have a FEZ Domino on it's way to me with a dead NXP ARM7 on it, and a replacement ARM chip, i might have to do a tutorial on how to solder it.
0603's and above are easy with a pair of surface mount tweasers. If you're really worried about the board, get one made at PCBCart.com, then head over to SMTStencil.com and get a stencil made. Buy some solder paste, stencil on the solder paste, place your parts with surface mount (self closing) tweasers and then heat with a hot air gun slowly until the solder goes all liquid.
Surface mount isn't something to be afraid of, i only first got PTH parts after getting a FEZ Domino and a Sparkfun Inventors Kit... I've been doing surface mount only boards for 4 years - it's what i learnt on.
I'd love to see a tutorial on surface mount soldering...
There are heaps of them on YouTube, but i'll see what i can do once i get the domino and usbizi chip in Failing that, i can just put some FT232RL's on boards, they have the same pin pitch.

Have been soldering surface mount for a year now, all with just a normal soldering iron. I now ordered some FEZ Domino pcb's and some of those 144 pins LQFP ARM7 chips, I have to say I'm not really sure what the best way is to solder those things. I have no problems with any other parts so far, but this is going to be a challange I guess. I have recently bought a Aoyue 968 hot air soldering station and I hope I can use that thing on those chips.. or do you think hand soldering is still the best way?
I just hand solder chips like that. Unless you have a stencil for a whole board i dont see much point in hot air. Just position the mcu on the board and hold it down with something (self closing tweasers) and then tack opposite corners, checking alignment before doing each one. Then just run solder along the pins - using surface tension to keep the blob from creating bridges and then remove the bridge from the last two pins if you made one with the remains of the blob.
Mark, are you planning on making eagle files for the Netduino Plus? I would love to make my own boards, but I do not have the skills to make those designs myself Do you think it is possible to make 2 layer boards of the Netduino Plus, because if I understand correctly the Netduino Plus and the Netduino for that matter are 4 layer pcb's and those are very expensive to produce.
Thanks,
Ramon
I would be very interested in Eagle schematics. I have no plans to make a board but I am a visual guy and would find the schematic useful to my fully understanding it. I have a freeware version that I am just getting familiar with.
Thanks,
Justin
I have a schematic of the Netduino Mini on Eagle. No board, and it's the simplest to draw, but it's a start. Hopefully, you can export any components that aren't in your library.
I'm a newcomer to the hardware side, so there's no guarantees this schematic is completely accurate, either.
