Wiring Diagrams

I thought I`d start a page on the diagrams I`m making. This first set is for DOSD. After a potential problem was discovered recently these new diagrams will enable you to wire up the DOSD perfectly safely avoiding the potential problem.

Ok first the most common application :

Easystar Basic

Spec :

3 Channel control, Throttle Rudder and Elevator controlled by DOSD
FPV system isolated from ESC circuit
12v Camera
12v Vtx
Dragon Link UHF

System supports : Gps based flight stabilization, RTH with speed control, programmable missions capable



Easystar Basic

Delta Wing Basic

Spec :

12 v Camera
12v VTX
Isolated BEC circuit.
Isolated ESC Circuit
Fully filtered ( Camera, OSD, Vtx and Bec Circuit )
DOSD Powered of filtered current sensor wire and jumper
BEC supplies PWM 4 ( not used )
Only signal wire from ESC used

Completely safe

Note : The shielded wires are not joined at the BEC, this stops a ground loop, both wires going to BEC are part of the shield system though

Delta Wing

Twinstar

System 1 : Basic 4 Channel Setup

Spec :

Full Aileron, Elevator, Rudder and Throttle control via DOSD
Camera, Vtx and BEC Filtered ( Bec`s not needed but easier for wiring )
12v Camera
12v Vtx

Completely safe.
Isolated FPV circuit from ESC`s

System supports : Gps based flight stabilization, RTH with speed control, programmable missions capable

Twinstar




System 2 : Twinstar with IMU and Mic

Spec :

Full Aileron, Elevator, Rudder and Throttle control via DOSD
Camera, VTX, Mic, IMU and BEC supply Filtered

12v Camera
12v Vtx
12v Mic
5v IMU ( Optional )
Step-up for Camera ( Optional )

Completely safe.
Isolated FPV circuit from ESC`s

System supports : Gps and IMU based flight stabilization, RTH with speed control, programmable missions capable, artificial horizon

Twinstar with IMU and Mic

Skywalker system

After the ground loop potential problem i went against my norm and decided on a 2 lipo system. Power and Video

Spec :

Seperate Video and Power system
Seperate standalone BEC circuit
No modification to DOSD wiring connections other than no -ve and +ve from Esc`s Bec wire
Should be no need for any filtering
2 Voltage readings, 1 for video 1 for power

Full Aileron, Elevator, Rudder and Throttle control via DOSD

12v Camera
12v Vtx

Completely safe.
Isolated FPV circuit from ESC

System supports : Gps based flight stabilization, RTH with speed control, programmable missions capable

Skywalker
