Voltage&Current Monitoring

	Ardupilot	PX4	Betaflight	INAV
Voltage Factor	21.12	21.12	211	211
Current Factor	14.14	14.14	707	707

 

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)

UART Mapping (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 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 SERIAL6 _Protocol to something other than 23.

 

OSD Support  (Ardupilot)

The MicoAir743v2-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.

 

PWM Output

The MicoAir743v2-AIO supports up to 9 PWM outputs.

Channels 1-8 support DShot/bi-directional DShot.

(currently PX4&INAV not support BDShot function)

PWM output share grouped and every group must use the same output protocol:

1,2,3,4 are group 1

5, 6 are group 2

7,8, 11are group 3

Note: PWM11 is the ¡°LED¡± pin. If this is configured for serial LED use then PWM 7 and 8 can only be used as serial LED also.

 

Compass

The MicoAir743v2-AIO doesn¡¯t have a built-in compass sensor, but you can attach an external compass using I2C on the SDA and SCL connector.

 

Physical

• Mounting: 25.5 x 25.5mm, ¥Õ3mm
