The wireless module must sustain a transmission rate that allows for image data to be transferred in real-time.

The camera must be able to capture VGA image data (640x480) at 30 fps.

The JPEG encoder must be able to compress the image data real-time to meet transmission requirements.

The microcontroller must support serial interfaces for the autopilot, wireless module, camera, and JPEG encoder.

Goal: Provide high data rate transmission in long range application

Xbee RF module provides up to one mile range at 250 kbps maximum data rate.

3.3 Volt CMOS UART interface

Sleep mode for extending the battery life

Goal: Provide at a minimum 15 fps and output a VGA signal

Toshiba CMOS camera module can capture up to 30 fps. Uses an SPI interface to output data.

640x480 resolution

Image compression required to meet RF module data rate requirements.

Analog devices ADV212 JPEG encoder alleviates the need to implement encoding on the microcontroller.

Microcontroller required to store data image to send to the RF device

64kB SRAM 66 Mhz Provides I/O to

interface with other components
