UART Mapping

Ardupilot: SERIAL0 USB SERIAL1 UART1 (MAVLink2, DMA-enabled) SERIAL2 UART2 (DisplayPort, DMA-enabled) SERIAL3 UART3 (GPS, DMA-enabled) SERIAL4 UART4 (MAVLink2, DMA-enabled) SERIAL5 UART5 (DMA-enabled) SERIAL6 UART6 (RCIN, DMA-enabled) SERIAL8 UART8 (DMA-enabled)
PX4: ttyACM0 USB ttyS0 TELEM1 UART1 ttyS1 GPS2 UART2 ttyS2 GPS1 UART3 ttyS3 TELEM2 UART4 ttyS4 TELEM3 UART5 ttyS5 RC UART6 ttyS7 TELEM4/SERIAL4 UART8

RC Input (Ardupilot)

The default RC input is configured on UART6. The SBUS pin is inverted and connected to RX6. Non-SBUS, single-wire serial inputs can be tied directly to RX6 if the SBUS pin is left unconnected. RC can also be used on UART2, UART4, or UART8 by setting SERIALn_PROTOCOL=23 and changing SERIAL6_PROTOCOL to a different value.

OSD Support (Ardupilot)

Supports OSD using OSD_TYPE 5 (MSP_DISPLAYPORT).

VTX Support

SH1.0-6P connector supports DJI Air Unit / HD VTX connection (DisplayPort protocol). Pin 1 supplies 12V ensure compatibility before connecting devices that require 5V.

PWM Output

Supports up to 9 PWM outputs. Channels 18 support DShot and bi-directional DShot (BDShot) Note: PX4 & INAV currently do not support BDShot
Output Groups: Group 1: PWM 1, 2, 3, 4 Group 2: PWM 5, 6 Group 3: PWM 7, 8, 11 (Note: PWM11 is LED. If used for serial LED, PWM7 and PWM8 must also be used for LEDs)

Compass

No built-in compass. External compass can be connected via I2C on SDA/SCL.

Q: Im having trouble connecting my AM32 ESCs when using ArduPilot firmware. What should I do?

A: First, update your Micoair H743 V2 AIO flight controller to the latest firmware and configure the communication parameters according to the official ArduPilot setup guide.

In rare cases, users may experience connection issues between ArduPilot and AM32 ESCs. This is a firmware compatibility issue, not a hardware fault. The ArduPilot team is actively improving compatibility.

If the problem persists, temporarily flash Betaflight (BF) or INAV firmware to complete ESC configuration, then re-flash ArduPilot. This workaround has been effective. Future ArduPilot releases should resolve the issue.
