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.

Sample Wiring Diagram
Building Firmware
To build PX4 for this target:
sh
make micoair_h743-lite_defaultInstalling PX4 Firmware
The firmware can be installed in any of the normal ways:
Build and upload the source
shmake micoair_h743-lite_default uploadLoad the firmware using QGroundControl. You can use either pre-built firmware or your own custom firmware.
INFO
At time of writing the only pre-built software is
PX4 main(see Installing PX4 Main, Beta or Custom Firmware). Release builds will be supported for PX4 v1.17 and later.
Radio Control
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.
Supported Platforms / Airframes
Any multicopter / airplane / rover or boat that can be controlled with normal RC servos or Futaba S-Bus servos. The complete set of supported configurations can be seen in the Airframes Reference.
