ADC with the Stamp XL

Because the QFN-80 places the ADC pins A0-A3 in a different position, it is required to cut and resolder the ADC jumpers on the back of the Carrier when using an XL-size Stamp.

Cut the bridge that shorts the middle pad with the Standard side and solder the middle and XL pads together.
