I am really excited about getting my Netduino Plus 2. So I thought that in order to pass the insane long wait of 2 day shipping, that I would create a pinout reference sheet. Also, I need to have these things printed and beside me at all times to help my failing memory. One community user gave me a great idea, and suggested laminating it, which I will be doing in the near future. But before I do that please let me know if you notice any errors or would like to have anything added or changed and I will do my best to update it for you.

Just in case you're wondering, the image is intentionally large, however it makes it difficult to move around using the forum's lightbox. To open the pinout zoomed out, click here: Netduino Plus 2 Pinout

If you have found it at all useful, please let me know! And as always I would love to see what your making with your Netduino Plus 2. Posted Image

Edit: New pinout diagram Ver. 1.2

Great work, but I think you are one serial port short of a diagram :blink: I2C doubles up as Uart 4. Could we have a note on how the IORef works... Paul

Nice, Steve! Thanks for making this pinout reference! Chris

I2C doubles up as Uart 4.

Good catch Paul. You pay attention to the details!

Paul, I knew I should have checked with you before I posted :)

I have updated the pinout, and hopefully have the order correct for the RX and TX. If not please let me know.

As for the IOREF, I would be more than willing to add a brief note, if someone were to supply me with one. :) I've read through the posts discussing it, and given that it's nearly 3:00am here, my brain is unable to muster up an intelligent short note to add.

Cheers,
Steve

Is this diagram perpetuating the myth of COM2 RTS/CTS functionality or is hardware flow control actually working on the NP2? Please see the discussion at http://forums.netdui...ts-always-high/ and the bug at http://netduino.code...com/workitem/5. As far as I can tell, there has never been a shred of evidence supporting the claim that hardware flow control has ever worked on Netduino Plus and I assume that the same is true for Netduino Plus 2. If somebody can prove otherwise for NP2, it would make my day.

Hi Spork,

If somebody can prove otherwise for NP2, it would make my day.

I believe there was a hardware errata for RTS/CTS on the SAM7X MCU we used on Netduino Plus 1. The chip on Netduino Plus 2 is brand new and RTS/CTS should be working.

If they're not working, we'd like to fix that :)

Very nice, those reference sheets should be linked to on the product specifications pages. Thanks a lot Steve.

Pictures like this should be on the productpages, so it would be easy to find, this kind of references is extremely useful when trying to find out what is where, and I really like the way you mark pins with multiuse.

Wish someone could do this properly in arduino world also.. this is the best we got on the Due so far:

(look at that cortex-jtag, one of the pins you mark as gnd, is marked n/c there, what is correct?)

Steve, Great job as usual. I was wondering if you were going to take one of the many hints. :rolleyes: But I think that you may have been a little to fast. You could have waited a few more days, then explained that if Chris had sent you a pre-release Neduino Plus 2 you could have had the pinout ready on release day. That way you could have the new products before everyone, except maybe Stefan. B) Thanks, Chuck

Hi neslekkim,

Yes the pinout for the Cortex Debug Port does list it as N/C (No Connect or Not Connected), however in the Netduino Plus 2 schematic this pin is pulled to ground. I believe, and I feel I may need to be corrected on this one, that on the Cortex Debug Port the 7th pin is sometimes termed as a Key and is there only to properly orient the connector.

Cheers,
Steve

See Chuck, that's why I need to hire you as my manager. You always have the greatest ideas :D

BTW, did you get your NP2 this Saturday?

aha, I have newer found the proper layout for this connector, if it is meant for key, that would be great, then we could snip it of, and put something into the connector. (I have bought an 20pin - 10pin adapter, but not dared to use it yet since i cannot verify pins and orientation on it, hopefully I someday find that doc so I can use it :) (oh yes, it was an cheapie from ebay) )

Yes, they were waiting patiently for me to get home on Sunday (had to go to Boca Raton on Saturday). Started playing with the last night.

I don't want to derail the topic of this thread, so let me just insert a few links...

Here's an official document detailing the MiniJTAG (formally "Cortex Debug Port) pinout:
http://infocenter.ar..._connectors.pdf

We went back and forth on whether to make the KEY pin "NC" or "GND". In the end we followed the standard used by chip manufacturers such as Cypress:
