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 1–8 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.
