heres my little playground.
it contains:
netduino mini
102x64 lcd - spi
9dof imu sensor module + barometric sensor - i2c
128kb eeprom - i2c
temerature sensor - analog
trackball connected to pcf8574 - i2c
mcp23017 - i2c
4bit 7 segment (not connected atm)
sd-card slot - spi
real time clock (drifting a lot, like 2-3 secs an hour ...) - i2c
cp2102 usb-uart bridge
ftdi usb-uart bridge
max232
one step up and one step down module for 3.3 and 5v power supply
not on the sceen: joystick and led matrix module.
soon ill add a spi master <-> spi master wireless chip (NRF24L01+)
maybe some pIR chips (but well, they work without netduino/uC also)
next month plans:
i2c camera module (to save some pictures on the sd card) - not doable
bluetooth module - i hope i can get it to programm my netduino w/o cable (!) - working
ENC28J60 network module (spi) - dont have ethernet cable right now
TEA5767 fm radio (i2c) - todo
ill make better pictures as soon as i get my hands on a real digicam, not webcam as of now
everything now is working ofc
(except the imu, need more code for them, in progress!) - imu working (at least i can read the basic values)
greetings
// edit: some video of my compass in action.
atm it sends its data per uart to pc, gets rendered there in xna
its on my old led matrix
//edit: COBS and a simple UART transport system added
// cobs is just ported from original author // damn - link is gona and i dont have it anymore
//edit multi I2c and temerature sensor code added, its a smooth sensor, change history lenght to //make it faster
//edit: i now hooked up my rgb matrix
its only 3bit color, but still impressive

i also designed an app with that i can create images in color for it, its still in progress
(i klick the pixels, it shift to the next aviable color, a button to save it to a file is missing)
i also made a small "testbench" wich connect per uart to my netduino, and is capable of read/write register for a specified device (in that case my gyro sensor)
//edit: change in uart.cs its better now > it waits till it actually received the data it expects
uart class deleted for now, it has a memory leak
//edit: drivers for the mcp3201 added - 12 bit external adc.
also the uart bug seems to only affect stm32, have to look further into that.
// edit: uploaded a fixed version of realtimeclock (ds1307)
