A minimum cable solution for UAV DevBoard

I hate all those cables invading our little planes !
I like the german expression which describes this situation : "Kabelsalat".
I'm sorry that still no one uses PPM connections (yes, this receiver has a PPM out on channel 12).

This is then the best solution I found to minimize the amount of cables to connect the receiver to the UDB.
The connection includes 5 channels in (throttle, ailerons, elevator, rudder and autopilot mode), receiver feeding, a board to connect pan/tilt camera servos for autonomous targeting firmware, extra servos feeding.

Please note that the connections are on the bottom of the UDB board. I modified the pins to use the UDB with the Oilpan, but in this case I'm not using it (the Oilpan).

Here is the complete connection.

All the system is feeded by the throttle out / ESC BEC (already extensively tested on my Arcus, in the standard "Kabelsalat" layout).

It could be simpler but for the moment I'm using a board I already made.

I crimp all the cables myself. This way I can have the exact length I want, avoiding unuseful extra copper on board.

After that it remains to connect servos, eventually telemetry (another 3 poles cable to a logger or OSD or ...), eventually a magnetometer (4 poles cable).

Hope this will help some and stimulate some others ;)

Best regards,

Very nice Ric !

Why not usign your PPM signal? I have a Futaba FP-R127DF receiver and I would love to find the PPM signal.

I think it's just a matter of investing some time on programming to use your receiver PPM signal and free some pins so you can use them for something else(like pitot tube, etc...)

I out of time now, lots of projects going on at the same time, but the first thing i'm going to work on is finding and capturing the PPM signal.

Anyway, great job with your cables I aways crimp mine cables too.

I also want as little wires as possible. Less wires means higher reliability.

In the hardware that I designed myself, I integrated lot of things on 2 boards:
* 1 bluetooth radio connection for all remote needs: manual control, telemetry, high level commands, etc...
* a powerfull motherboard (ARM7 + 8Mo RAM)
* the "failsafe" that cuts the power in case of bug, loose of radio connection, user need, etc...
* 6DOF imu
* 3D magnetometer
* 4 Devantech sonars

Note that this is for an indoor drone... I presented my project here:

Really very nice Ric :)
I am looking forward to have RC RX --> UAVDB PPM connection too. I am waiting only because I dont have any programmers background. Ric's solution goes half way to the functionality of PPM input.
Thank you
