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) #
- TELEM1 -> UART1
- TELEM2 -> UART2
- GPS1 -> UART3
- TELEM3-> UART4
- RC -> UART6
- ESC -> UART7
- TELEM4 -> UART8
Ports #
Note:
- Serial2 and DJI VTX connector share with UART2.
- SBUS and ELRS receivers are usually connected to the RC port (UART6), and SBUS only needs to connect the signal pin to RX6. However, for H743, the receiver can actually connect to any serial port.
- VBAT is the only power input interface that supports 3-6S battery(11.1-22.2V). Other pins cannot be connected to high voltage, otherwise it will directly burn the board.
