Hi, i've just ordered an Arduino mini (from robosavvy) and now i noticed that the Aref port in the schematics is not actually exposed as a pin that can be interfaced with.

I would like to interface with the IDG-300 gyro which outputs 0V- 1.23V and I would loose 2 bits of resolution if it is not possible to give the 1.23V as reference to the Aurdino's Atmega168

hi

to connect to AREF on the mini you would have to solder a wire onto pin 20 of the Atmega...
