📘 Documentation & Guides

H743 AIO — Full User Manual — specs, UART mapping, outputs, battery monitoring, and what an AIO trades away
AIO or a Stack? — the layout decision: compass, OSD, BEC current, heat and repair cost
ArduPilot Basic Configuration — frame type, DShot, motor order, calibration and first arming
Configure ESC Parameters — updating and configuring the on-board AM32 ESC through the flight controller
External Compass Orientation — required reading for an AIO, which has no internal compass to auto-detect against

Setting it up with an AI assistant? Read our AI setup guide first. It shows you how to point ChatGPT, Claude or Gemini at the official manual for this product, so the answers come from the real pinout and parameter names instead of guesses.

Battery Monitoring

ArduPilot / PX4: voltage factor 21.12, current factor 14.14 (BATT_VOLT_MULT / BATT_AMP_PERVLT on ArduPilot)
Betaflight / INAV: voltage scale 211, current scale 707

UART Mapping (Ardupilot)

SERIAL0 -> USB
SERIAL1 -> UART1 (MAVLink2, DMA-enabled)
SERIAL2 -> UART2 (VTX-HD, DMA-enabled)
SERIAL3 -> UART3 (GPS, DMA-enabled)
SERIAL4 -> UART4 (MAVLink2, DMA-enabled)
SERIAL5 -> UART6 (RCIN, DMA–enabled)
SERIAL6-> UART7 (ESC Telemetry, DMA-enabled)
SERIAL7 -> UART8 (DMA–enabled)

UART Mapping (PX4)

ttyACM0 -> USB
ttyS0 -> TELEM1 -> UART1
ttyS1 -> TELEM2 -> UART2
ttyS2 -> GPS1 -> UART3
ttyS3 -> TELEM3-> UART4
ttyS4 -> RC -> UART6
ttyS5 -> ESC -> UART7
ttyS6 -> TELEM4 -> UART8

RC Input (Ardupilot)

The default RC input is configured on the UART6. The SBUS pin is inverted and connected to RX6. Non SBUS, single wire serial inputs can be directly tied to RX6 if SBUS pin is left unconnected. RC could be applied instead at a different UART port such as UART2, UART4 or UART8, and set the protocol to receive RC data: SERIALn_PROTOCOL=23 and change SERIAL5 _Protocol to something other than 23.

OSD Support (Ardupilot)

The MicoAir743-AIO supports OSD using OSD_TYPE 5 (MSP_DISPLAYPORT).

VTX Support

The SH1.0-6P connector supports a DJI Air Unit / HD VTX connection. Protocol defaults to DisplayPort. Pin 1 of the connector is 12v so be careful not to connect this to a peripheral requiring 5v.
