The tables below give a summary of the analog inputs available on your AVR. Some of these pins are hardwired

or jumpered to the battery voltage or sensors or trimpots built in to your device, while other pins are available for

you to connect your own sensors to. Please refer to the pin assignment table in the user’s guide for your device

for more information.
