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



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