|
|
::: warning
|
|
PX4 does not manufacture this (or any) autopilot.
|
|
:::
|
|
|
|
The AP-H743-R1 is an advanced autopilot manufactured by X-MAV<sup>®</sup>.
|
|
|
|
The autopilot is recommended for commercial system integration, but is also suitable for academic research and any other applications.
|
|
It brings you ultimate performance, stability, and reliability in every aspect.
|
|
|
|
|
|
|
|
::: info
|
|
These flight controllers are [manufacturer supported](../flight_controller/autopilot_manufacturer_supported.md).

## Purchase Channels {#store}
|
|
|
|
Order from [X-MAV](https://www.x-mav.cn/).
|
|
|
|
## 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).
|
|
|
|
You will need to select a compatible transmitter/receiver and then bind them so that they communicate (read the instructions that come with your specific transmitter/receiver).
|
|
|
|
SBUS receivers connect to the SBUS-IN input port.
|
|
CRSF receiver must be wired to a spare port (UART) on the Flight Controller. Then you can bind the transmitter and receiver together.
|
|
|
|
## Serial Port Mapping
|
|
|
|
| UART | Device | Port |
|
|
| ------ | ---------- | ------- |
|
|
| USART1 | /dev/ttyS0 | GPS |
|
|
| USART2 | /dev/ttyS1 | GPS2 |
|
|
| USART3 | /dev/ttyS2 | TELEM1 |
|
|
| UART4 | /dev/ttyS3 | TELEM2 |
|
|
| UART7 | /dev/ttyS4 | TELEM3 |
|
|
| UART8 | /dev/ttyS5 | SERIAL4 |
|
|
|
|
## PWM Output
|
|
|
|
The AP-H743-R1 flight controller supports up to 15 PWM outputs.
|
|
The first 8 outputs (labelled M1 to M8) are controlled by a dedicated STM32F103 IOMCU controller.
|
|
The remaining 7 outputs (labelled A1 to A7) are the "auxiliary" outputs.
|
|
These are directly attached to the STM32H743 FMU controller .
|
|
|
|
The 15 PWM outputs are:
|
|
|
|
M1 - M8 are connected to the IOMCU.
|
|
A1 - A7 are connected to the FMU.
|
|
|
|
M1 - M8 support DShot and are in 3 groups:
|
|
|
|
- M1, M2 in group 1
|
|
- M3, M4 in group 2
|
|
- M5, M6, M7, M8 in group 3
|
|
|
|
The 7 FMU PWM outputs are in 3 groups:
|
|
|
|
- A1 - A4 are in one group.
|
|
- A5, A6 are in a 2nd group.
|
|
- A7 is in a 3rd group.
|
|
|
|
Channels within the same group need to use the same output rate.
|
|
If any channel in a group uses DShot then all channels in the group need to use DShot.
|
|
|

|
|
|
|
## Battery Monitoring
|
|
|
|
The board has connectors for 2 power monitors.
|
|
|
|
- POWER1 -- ADC
|
|
- POWER2 -- DroneCAN
|
|
|
|
The board is configure by default for a analog power monitor, and also has DroneCAN power monitor configured which is enabled.
|
|
|
|
## Building Firmware
|
|
|
|
To [build PX4](../dev_setup/building_px4.md) for this target, execute:
|
|
|
|
```sh
|
|
make x-mav_ap-h743r1_default
|
|
```
|
|
|
|
## Pinouts and Size
|
|
|
|
|
|
|
|
|
|
|
|
## Supported Platforms / Airframes
|
|
|
|
Any multirotor/airplane/rover or boat that can be controlled using normal RC servos or Futaba S-Bus servos.
|
|
The complete set of supported configurations can be found in the [Airframe Reference](../airframes/airframe_reference.md).
|
|
|
|
## Debug Port {#debug_port}
|
|
|
|
### SWD
|
|
|
|
The [SWD interface](../debug/swd_debug.md) operate on the **FMU-DEBUG** port (`FMU-DEBUG`).
|
|
|
|
The debug port (`FMU-DEBUG`) uses a [JST SM04B-GHS-TB](https://www.digikey.com/en/products/detail/jst-sales-america-inc/SM04B-GHS-TB/807788) connector and has the following pinout:
|
|
|
|
| Pin | Signal | Volt |
|
|
| ------- | --------- | ----- |
|
|
| 1 (red) | 5V+ | +5V |
|
|
| 2 (blk) | FMU_SWDIO | +3.3V |
|
|
| 3 (blk) | FMU_SWCLK | +3.3V |
|
|
| 4 (blk) | GND | GND |
