Compatible Shields and Accessories

I would read the specs more carefully.
Actually when ordering arduino shields make sure you check the amount of current that the shield requires from the pins, since arduino allows up to 40mA per I/O pin where as netduino only allows 8mA per I/O pin which is 5x less.
The ARM specs (Netduino MCU) offer various sink capabilities, depending on the pin. The sink can vary from 2 to 16mA.
The AVR specs (Arduino family) state that the absolute maximum ratings (to avoid due the high stress) is 40mA on a generic pin. It means the capability of a generic pin, as if was take alone.
If you read further, there are two interesting points.
First off, the specs state:
Although each I/O port can source more than the test conditions (20 mA at VCC = 5V, 10 mA at VCC = 3V) under steady state
conditions (non-transient), the following must be observed:
1] The sum of all IOH, for ports C0 - C5, D0- D4, ADC7, RESET should not exceed 150 mA.
2] The sum of all IOH, for ports B0 - B5, D5 - D7, ADC6, XTAL1, XTAL2 should not exceed 150 mA.
Secondly, take a look at the charts of the sink current vs output voltage. It clearly consider a sink up to 20mA.
The problem is NOT the current, but the power that will overheat the chip core!
Take the heating power for one pin and multiply for the numbers of outputs. The higher is the number of outputs, the lower must be the upper bound of the max current allowed.
Finally, an Arduino shield asking 40mA for a pin it's probably garbage.

It looks as a standalone product (it embeds an Arduino). I wasn't able to find what an external controller should do.
Would this Camera Axe Shield be compatible with netduino?

Sparkfun Ardumoto Motor Driver Shield:
This shield is not directly compatible with the Netduino. It expects PWM interface on data pins 3 and 11. The Netduino does not support PWM on those pins. So I bent those pins over on the underside of the board to prevent that connection and jumpered those connections to data pins 9 and 10 where the Netduino can provide PWM.
There is also a solder jumper "V-Logic" which must be changed from it's delivered setting of 5V to instead use 3.3V logic levels compatible with the Netduino.
Other than that, usage was straight-forward.
Details and photos can be found at my website.
I also changed the voltage selector to 3.3V, but then changed it back after reading the data sheet for the L298. The data sheet indicates that 5V is required (4.5 to 7V). I don't know why the selector is fitted.

I would really appreciate it if someone could confirm that the following colored LCD shields are Netduino compatible:
-First one is the seedstudio TFT shield
-Second one is the all known Sparkfun Color LCD Shield
I did a research about the compatibility issues but would like a confirmation from more experienced users.
Many thanks in advance.

-I am interested in managing colored LCD with netduino, but as msakms, I am not sure on what is compatible :
My feeling is that the examples of msakms are electrically compatible, but that there is no (not yet?) C# interface to use them with Netduino! (but maybe it is not so hard to develop C# interface for them?)
-I guess that the ITDB02 Arduino Shield v1.3 and the 2.8" TFT LCD screen Module ITDB02-2.8 should either be "electrically" OK.
->Edit : I have tested the 2.8" TFT LCD screen Module ITDB02-2.8 -> I confirm that it works, but veeeery slowly . In fact have adapted in C#-netduino the arduino exemple provided by itead studio here
->The issue is that we have no quick access to 8-bit bus and then we must set this bus pin after pin, wich is slow (I measure that a pin can't go faster than 8.2Khz, so with 320*240*16bits color screen, it takes more than 2 minutes to fill screen with a picture . Maybe with some native code dev. it would be faster!
-There is either the shield posted by Sim in 2010 wich seems to be okay (just need to reroute the CS pin):
Hello, this is my first post from Japan.
Recently I get TFT-LCD shield for Arduino. When the TFT-LCD shield was used with Netduino, I met the problem. By information from this forum, I solved the problem. Thanks lynxeyed_atsu and Chris. TFT-LCD shield use pin4 as SPI chip select. Netduino can only select pin10 as CS.
My conclusion is that TFT-LCD shield is almost compatible shield.

Here are a few Adafruit shields that we've been successfully using in the lab:
Adafruit proto shield
Adafruit GPS logger shield (GPS connectivity + SD card)
NOTE: SD card feature requires Netduino v4.1.1 (Alpha 1) or newer firmware.
Adafruit data logging shield (SD card + real-time clock)
NOTE: there are drivers for this RTC (if someone has a link, we'll add it here).
Oh good grief! I have here two of those Adafruit Proto shields. I bought them from the same place as three of the RGB LED devices that (I believe) you used for the example. That was the computer store for NYU, they sell large quantities of the stuff to the ITP community, and as it happens to anyone else. (When I bought everything I was asked if I had an ID. I do not as I am not a student of Mr Gallatin's school. Then that happened: When I bought an Arduino from them, the one that means 2009 in Italian, the seller who himself was from that region muttered something rude in Italian under his breath. I didn't ask for a translation. )
I was afraid that when I decided that I would need to buy a regular Netudunio because I've discovered that some of the examples work better on it, I would need to buy yet another one, the Sparkfun style as it happens. That one was chosen because the store Microcenter as it happens sells that one. ( Here it is. ) That guy looks the same as the Adafruit one except its colored in Sparkfun red.
SPF also sells a MicroSD card shield, which is this thing, which I believe would support your position Chris on how to have the unit work with Mono.
Incidentally the price for the SPF protoshield in retail packaging at that store is the same as the one sold from the website.
I also bought the Netdunio Mini from the same store.
The other two I've not as yet found a need for.
Also SPF sells a board which is simply a LiPo powerpack for the Ardunio, I've never tried it so I do not know if it would work to run the boards......

This shield isn't exactly one per se the board in question accepts the host in the normal position. But here goes:
Parallax BOE for Arduino
Basically it provides everything that users for the original for the Stamp2 would find on the BOE but for the Arduino, and as it happens for the Netduino. I found the two listed for sale at the same Microcenter store where I bought both Netduinos, the Mini and the regular sized one. I had originally thought of building something similar, that is a board wearing the pins in matching positions, and brought out to connectors and a breadboard there as well. (The servo connectors and other things would not be needed.)
The same company sells kits to turn a BOE into a robot of sorts, either wheels or tracks or even a crawler using legs. I had thought of using a similar method for one as described here:
Android G1 Serial To Arduino Robot
The base resembles the BOE bot with tracks but so far the author hasn't explained what the whole business is standing on. The company who makes the tracks also makes a base for the tracks. Ideally the Arduino being used would be replaced by the Netduino. Problem? The programming.
Chris this may not properly fit in with the theme of this thread but I hope you accept it within its own merits. Stefan same here.

This Arduino XBee Shield is compatible. This shield working well.I 've been successfully using in my project.
Volkan, I am trying to use this shield, does it just stack right on top of the netduino or did you have to make modifications?
How did you get this to work? Any information on it would be fantastic!
I have this - Arduino Wireless SD Shield :
