AVR2016
The AVRRAVEN has been designed to run from two 1.5V LR44 battery cells.
An onboard voltage regulator makes it possible to run power the AVRRAVEN from a
5 to 12 Volts DC source. The external voltage is applied to the two leftmost pins in the
user IO area (J401). The ATmega3290P’s ADC channel 2 is connected to a voltage
divider and the external voltage supply interface. This way it is possible for the
application to monitor the external operating voltage.
The AVRRAVEN module has multiple interfaces that can be used for serial
communication, interaction with external sensors and control units such as relays and
of course programming and debugging.
