## UART Mapping
|
|||
|
|
The UARTs are marked Rn and Tn in the above pinouts. The Rn pin is the receive pin for UARTn. The Tn pin is the transmit pin for UARTn.

|

|
|
## RC Input
|
|||
|
|
The RCIN pin, which by default is mapped to a timer input, can be used for all ArduPilot supported receiver protocols, except CRSF/ELRS and SRXL2 which require a true UART connection. However, FPort, when connected in this manner, will only provide RC without telemetry.
|
|||
|
|
|
|||
|
|
To allow CRSF and embedded telemetry available in Fport, CRSF, and SRXL2 receivers, a full UART, such as SERIAL5 (UART8) would need to be used for receiver connections. Below are setups using Serial5.
|
|||
|
|
|
|||
|
|
* :ref:`SERIAL5_PROTOCOL<SERIAL5_PROTOCOL>` should be set to “23”.
|
|||
|
|
* CRSF would require :ref:`SERIAL5_OPTIONS<SERIAL5_OPTIONS>` set to “0”.
|
|||
|
|
* SRXL2 would require :ref:`SERIAL5_OPTIONS<SERIAL5_OPTIONS>` set to “4”. And only connect the TX pin.
|
|||
|
|
|
|||
|
|
* The SBUS_IN pin is internally tied to the RCIN pin.
|
|||
|
|
|
|||
|
|
Any UART can also be used for RC system connections in ArduPilot and is compatible with all protocols except PPM. See :ref:`Radio Control Systems <common-rc-systems>` for details.

## PWM Output
|
|||
|
|
The SULILLGH7-P1/P2 flight controller supports up to 16 PWM outputs.
|
|||
|
|
First 8 outputs (labelled 1 to 8) are controlled by a dedicated STM32F103 IO controller.
|
|||
|
|
The remaining 8 outputs (labelled 9 to 16) are the "auxiliary" outputs. These are directly attached to the STM32H753 FMU controller.
|
|||
|
|
All 16 outputs support normal PWM output formats. All 16 outputs support DShot, except 15 and 16.
|
|||
|
|
|
|||
|
|
The 8 IO PWM outputs are in 4 groups:
|
|||
|
|
- Outputs 1 and 2 in group1
|
|||
|
|
- Outputs 3 and 4 in group2
|
|||
|
|
- Outputs 5, 6, 7 and 8 in group3
|
|||
|
|
|
|||
|
|
The 8 FMU PWM outputs are in 4 groups:
|
|||
|
|
- Outputs 1, 2, 3 and 4 in group1
|
|||
|
|
- Outputs 5 and 6 in group2
|
|||
|
|
- Outputs 7 and 8 in group3
|
|||
|
|
|
|||
|
|
Channels within the same group need to use the same output rate. If any channel in a group uses DShot then all channels in the group need to use DShot.
|
|||
|
|
|
|||
|
|
## GPIO
|
|||
|
|
All PWM outputs can be used as GPIOs (relays, camera, RPM etc). To use them you need to set the output’s SERVOx_FUNCTION to -1. The numbering of the GPIOs for PIN variables in ArduPilot is:

## Battery Monitoring
|
|||
|
|
Two DroneCAN power monitor interfaces have been configured
|
|||
|
|
These are set by default in the firmware and shouldn't need to be adjusted.
|
|||
|
|
|
|||
|
|
## Compass
|
|||
|
|
The P1/P2 flight controllers have an integrated IST8310 high-precision magnetometer.
|
|||
|
|
|
|||
|
|
## Analog inputs
|
|||
|
|
The P1/P2 flight controller has 2 analog inputs.
|
|||
|
|
- ADC Pin12 -> ADC 6.6V Sense
|
|||
|
|
- ADC Pin13 -> ADC 3.3V Sense
|
|||
|
|
- RSSI input pin = 103
|
|||
|
|
|
|||
|
|
## Loading Firmware
|
|||
|
|
|
|||
|
|
The board comes pre-installed with an ArduPilot compatible bootloader, allowing the loading of xxxxxx.apj firmware files with any ArduPilot compatible ground station.
|
|||
|
|
|
|||
|
|
Firmware for these boards can be found [here](https://firmware.ardupilot.org/) in sub-folders labeled “SULIGH7-P1-P2”.
