Hello,

We're wondering about the legality of the Avago ADNS3080 high-performance mouse sensor, available on a breakout designed by 3D Robotics. It can be purchased at http://store.jdrones.com/Optical_flo.../senopt01a.htm, and from many other sources.

This module has 5V-compatible digital logic pins exposed, which are used to communicate with the sensor over the SPI bus.

Apart from whether or not a software implementation of SPI is feasible, would it be legal to connect these 5V-compatible digital logic pins to the digital I/O pins on the Core Device Interface?

Thanks,
Evolution Robotics, team 9867
