Connectors & Pinout
Board uses JST SH connectors for all interfaces.


Note - SBus pin on DJI O3/O4 port is internally connected to RX6 (RCIN).
PWM Виходи
The 8 outputs are in 3 groups:
- Outputs 1-4 in group1
- Outputs 5-6 in group2
- Outputs 7-8 in group3
Note:
- All outputs support PWM and DShot protocol. Outputs 1-6 and 8 support "bidirectional DShot" (or "BDShot") telemetry.
- Outputs 1-4 default to DShot300 (PWM_MAIN_TIM0 =
-4); outputs 5-6 and 7-8 default to PWM at 400 Hz. - Each group's protocol can be changed independently using the corresponding
PWM_MAIN_TIMxparameter, including to Bidirectional DShot (BDShot) for ESC telemetry.
Відладочний порт
This board does not configure a dedicated UART as a system console. Use the MAVLink Shell over USB for console/NSH access using QGroundControl.
SWD
The board features a 4-pin SWD Debug interface (3V3 / SWCLK / SWDIO / GND) for hardware debugging.
Радіоуправління
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). See Radio Control modules for the list of supported protocols.
RC input is mapped to USART6 (/dev/ttyS4, RC port). The port supports both single-wire inverted SBUS and full-duplex protocols with telemetry return (such as CRSF), and the receiver protocol is auto-detected by default (RC_INPUT_PROTO = -1).
Конфігурація PX4
In addition to the basic configuration, the following parameter is important:
| Parameter | Налаштування |
|---|---|
| SYS_HAS_MAG | Disabled by default since the board has no internal magnetometer. Enable it if you attach an external mag. |
Збірка прошивки
To build PX4 for this target:
make zenfc_h743_defaultВстановлення прошивки PX4
Прошивку можна встановити будь-якими звичайними способами:
Збудуйте та завантажте джерело:
shmake zenfc_h743_default uploadLoad the firmware using QGroundControl. Ви можете використовувати або готове вбудоване програмне забезпечення, або власне користувацьке програмне забезпечення.
The board uses the standard PX4 bootloader, so it follows the same generic LED indications as most other boards (Red = Bootloader/Error, Blue = Active/Activity, Green = Powered).
