MicoAir743-Lite

main (planned for: PX4 v1.17)

WARNING

PX4 does not manufacture this (or any) autopilot. Contact the manufacturer for hardware support or compliance issues.

MicoAir743-Lite is an ultra-high performance H743 flight controller with an unbeatable price, featuring the ICM45686 IMU sensor and integrated Bluetooth telemetry.

Equipped with a high-performance H7 processor, the MicoAir743-Lite features a compact form factor with SH1.0 connectors (which are more suitable than Pixhawk-standard GH1.25 for this board size). When paired with with Bluetooth telemetry, the board can be debugged with a phone or PC.

INFO

This flight controller is manufacturer supported.

무선 조종

A Radio Control (RC) system is required if you want to manually control your vehicle (PX4 does not require a radio system for autonomous flight modes).

The RC port is connected to the FMU and you can attach a receiver that uses the protocols DSM, SBUS, CSRF, GHST, or other protocol listed in Radio Control modules. You will need to enable the protocol by setting the corresponding parameter RC_xxxx_PRT_CFG, such as RC_CRSF_PRT_CFG for a CRSF receiver.

지원 플랫폼 및 기체

일반 RC 서보 또는 Futaba S-Bus 서보로 제어 가능한 모든 멀티콥터/비행기/로버 또는 보트. The complete set of supported configurations can be seen in the Airframes Reference.
