|
||
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](../flight_controller/autopilot_manufacturer_supported.md).

## Sample Wiring Diagram
|
||
|
||
|
||
|
||
## Building Firmware
|
||
|
||
To [build PX4](../dev_setup/building_px4.md) for this target:
|
||
|
||
```sh
|
||
make micoair_h743-lite_default
|
||
```
|
||
|
||
## Installing PX4 Firmware
|
||
|
||
The firmware can be installed in any of the normal ways:
|
||
|
||
- Build and upload the source
|
||
|
||
```sh
|
||
make micoair_h743-lite_default upload
|
||
```
|
||
|
||
- [Load the firmware](../config/firmware.md) 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](../config/firmware.md#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](../getting_started/rc_transmitter_receiver.md) 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](../modules/modules_driver_radio_control.md).
|
||
You will need to enable the protocol by setting the corresponding parameter `RC_xxxx_PRT_CFG`, such as [RC_CRSF_PRT_CFG](../advanced_config/parameter_reference.md#RC_CRSF_PRT_CFG) for a [CRSF receiver](../telemetry/crsf_telemetry.md).
|
||
|
||
## 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](../airframes/airframe_reference.md).
