[PIXHAWK] 픽스호크 PX4 오토파일럿 2.4.8 32bit ARM 비행 컨트롤러 (KC 인증)

KC 인증번호 : R-R-FwT-2020Pixhawk1

[ PX4  사용시 주의사항 ]

* 픽스호크 2.4.8 은 10년 이상 된 구형 하드웨어입니다.

2025년 현재 아두파일럿(Ardupilot) 펌웨어는 정상적으로 지원 및 작동하고 있으나,

PX4 펌웨어는 최신 버전에서 오류가 잦아서 정상적으로 지원되지 않습니다.

픽스호크 2.4.8 에 꼭 PX4 를 사용하시려면 버전 1.13.3 이하를 사용하시는 것을 권장드립니다.

픽스호크 2.4.8 은 전압 불안정으로 인해 PX4 사용시 Avionics Power Low 메세지가 출력되면서 시동이 안걸립니다. 

CBRK_SUPPLY_CHK = 894281, COM_POWER_COUNT = 0 으로 설정하여 이 메세지를 무시할 수 있습니다. 

안전스위치(Safety Switch)를 미사용하고 싶으시면 CBRK_IO_SAFETY = 22027 로 설정합니다. 

PIXHAWK is an advanced autopilot system of 3DR. It features transparent for hardware and convenient for re-development. PIXHAWK integrates with two advanced processor, STM32F103 backup failsafe 32-bit co-processor provides for manual recovery and has its own power supply if one processor breaks down, delivering incredible performance, flexibility, and reliability for controlling any autonomous vehicle. Users can also adjust the configurations of PIXHAWK according to different use and hobbies for different vehicles. In recent years, as one of the cores of autopilot system, PIXHAWK has gained a profound popularity among developers and hobbyists for being practical, easy to handle, economical.
