It would be tricky to support the shields. Arduino is 5V. The BeagleBone is 3.3V. So you would need bidirectional level shifting on all of the digital signals. Analog is only analog on the BeagleBone and limited to 1.8V.

Now, adding an Atmel processor onto the BeagleBone, that is easy and is already being done.

Ian,

i’ve already prototyped an arduino compatible cap using i2c gpio expander and ADCs. with this configuration it could be used with a wide range of platforms including a desktop pc with a usb->i2c adapter such as the FT2232
