Abstract
To meet requirement for data recording in modern micro unmanned aerial vehicle (UAV), a high-capacity data recorder based on PIC18LF4550 microcontroller and Flash memory is designed. Systematic plan and operation principle of all the modules are analyzed in detail. Four basic modules of the hardware of the data recorder are described, including the power transition module, communication interface module, flash memory module and mode-detection module. This data recorder has been tested in real time experiments. In the real time tests, the recorder can store data in a speed of 4000 Byte/s. The storage capacity of the recorder is up to 1 Gbyte while the power is low. These results show that the data recorder can fulfill the requirements of many micro UAVs for its large-capacity storage, low mass, and high speed.
