Axisflying Argus H743 45A AIO AM32

Axisflying Argus H743 45A AIO is an AIO board combining a flight controller and 4-in-1 45A ESCs. The board is suitable for 3-4" cinewhoops powered by 2-6S LiPo batteries, saving both space and weight compared to a separate stack. It supports both analog and digital video transmission.

The flight controller is based on the STM32H743 processor running at 480MHz, combined with an ICM42688P gyroscope. The board includes a DPS310 barometer for altitude measurement and 16MB memory for blackbox. There are 7 UARTs for connecting peripherals. The GPS module connects via UART3, the compass via I2C pads (SDA, SCL). Pads are also available for an LED strip, buzzer, and a button for bootloader mode.

Two BECs handle peripheral power – 5V/2A for the receiver, GPS and camera, and 12V/2A for the video transmitter. For proper operation of the 12V BEC, the board must be powered by at least a 4S LiPo battery. The board features a MAX7456 OSD chip for analog video, with pads for the camera and video transmitter. The digital video transmitter connects via a 6-pin connector, which also carries the SBUS signal for the DJI FPV Controller.

The board does not have an integrated receiver. An external RC receiver (ELRS, TBS Crossfire or SBUS) connects via a 4-pin connector on UART2. The same UART is also used by the SBUS wire in the digital system connector, so when using a standard receiver without the DJI FPV Controller, we recommend disconnecting the SBUS wire from the digital system cable. Otherwise, the receiver may not be recognized by the flight controller.

The ESCs use 32-bit AM32 firmware with support for bidirectional DShot and can handle up to 45A per channel. The board is equipped with a current sensor.

The mounting hole spacing is 25,5x25,5mm, the board dimensions are 36x36x8,4mm and the weight is 11,5g. In addition to the USB-C connector directly on the board, pads are available for an external USB-C that connects via an SH1.0 connector – especially useful on cinewhoops, where the board is often hard to access after assembly. The board is mounted on the included M2 silicone softmounts, which dampen vibrations.
