Figure 2-1. AVRRAVEN overview.
The AVRRAVEN hardware is based on two microcontrollers and one radio transceiver chip. The Atmel ATmega3290P
handles the sensors and the user interface and the Atmel ATmega1284P handles the Atmel 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.
