The AVRRAVEN hardware is based on 2 microcontroller and one radio transceiver
chip. The ATmega3290P handles the sensors and the user interface and the
ATmega1284P handles the AT86RF230 radio transceiver and the RF protocol stacks.
The MCUs and the radio communicate via serial interfaces.
For hardware details please refer to Appendix A for the complete AVRRAVEN
schematics.
