Hardware integration

Hardware recommendations and integration notices

Required hardware

• Multirotor frame with motors and props (defaults are based on 10" X-type quadcopter)

• Skynode S with supported MIPI camera and MIPI cable

• ESC: 4in1 that supports DSHOT protocol and Skynode S compatible JST-SH cable

• RC Receiver (optional): supporting CRSF or SBUS protocols

• Supported data link radio

• External compass (optional)

• GNSS receiver module (optional)

Wiring

For the wiring instructions refer to component specific documentation and Skynode S's Interfaces.

Motor mapping

The table below provides the default output mapping for Dragon SR, that can be used to prepare the cable to connect Skynode S with the 4in1 ESC

Some ESCs might have different motor numbering - please check!

Motor name	Skynode S PWM output	Typical ESC motor number
Front left	PWM1	4
Back left	PWM2	3
Front right	PWM3	2
Back right	PWM4	1

Motor name	Skynode S PWM output	Typical ESC motor number
Front left	PWM1	4
Back left	PWM2	3
Front right	PWM3	2
Back right	PWM4	1

Receiver wiring

The receiver can be connected to Skynode S in different ways, depending if telemetry and/or analog VTx is meant to be used.

Default: CRSF receiver without telemetry and analog VTx

The autopilot comes pre-configured for CRSF protocol based receivers connected to RC_In input on Skynode S EXTRAS 1 port. There is no additional configuration needed in that case.

CRSF receiver with telemetry and/or analog VTx is being used

In order to use CRSF telemetry connect the receiver to TELEM2 serial interface on EXTRAS 1. Refer to Radio Controller setup to configure the autopilot.

SBUS receiver

SBUS receiver can be connected to Radio Controller input of Skynode S interfaces. Additional software setup is required.
