I believe the Netduino 3 Wifi uses (correct me if I am wrong) this hardware: http://www.st.com/st.../DM00071990.pdf .
I was reviewing the built in peripherals and came across page 37+ (I am still reading the DS).
3.26-28 (various digital audio interfaces)
3.32 Controller area network (bxCAN)
3.33 Universal serial bus on-the-go full-speed (OTG_FS) (and 3.34 OTG_HS)
3.35 Digital camera interface (DCMI)
3.36 Random number generator (RNG)
3.39 Temperature sensor
It does note that it is really only good for relative temperature sensing. I haven't looked closely at the SecretLabs implementations of any of these, I suspect some of these might already be in use.
I only see is SecretLabs.NETMF.Hardware.Netduino:
AnalogChannels, BaudRates, InterruptModes, Pins, PWMChannels, ResistorModes, SerialPorts, SPI_devices
I would not imagine the CAN/DCMI/RNG or the audio interfaces be available anywhere else but this Assembly.
I am not even sure if there is connectivity for DCMI or (bx)CAN or the Audio or OTG in the existing schematic/layout -- but perhaps access to RNG and the relative temperature sensor would be of some interest/value to somebody.
Not really sure what value some of those have. I understand that some of the pins that bxCAN/DCMI/OTG_FS/DCMI/(the audio interfaces) can use are probably already in use with other functions and that it probably is impossible given the current board layout.
Just an observation / curiosity.
