Hi Chris, I’ve ordered a few netduino boards. It’s working great as a development board for a project we’re working on. I heard in an interview that netduino is an “open source” project. I was hoping to get the schematic files so that we can use them as a starting point for our project hardware. We need to add a bunch of comm ports, RAM, etc. and it would save us a lot of time. I see the .brd files are available online but it would be great if we could get the .sch file for the netduino plus for use in CadSoft Eagle. Cheers, Kenny

Hi Kenny,

Welcome to the Netduino community!

We use Candence Allegro for board layout on sophisticated boards like the Netduino. We do print the schematics out as PDFs, which are available on the Downloads page.

Does that give you a good start?

Any chance in providing PDF format files for the board layout of all three Netduino boards?

Hey Kenny,

FYI :

Chris said in this post the schematic is 4 layered so it isnt possible with free eagle version to handle 4 layers.

I see that Allegro supports exporting ODB++. Any chance you can post the boards in ODB++? Thanks

Slightly offtopic, would it be difficult to replace the ARM7 with say an ARM Cortex M3, with 1024 kb flash? I'm not a hw person (and my hw colleague is on vacation), but it seems to me that the M3 is rather similar to the ARM7.

Yes :) We're actually looking at creating a port for a Cortex M3 chip for another project here at Secret Labs.

The Cortex M3 is in many ways the "next generation" of the ARM7. Unfortunately, M3 chips are generally not 5V tolerant and most have less RAM than the SAM7X512 chip.
