[Sticky] SBUS to PWM Decoder
The FrSky S.BUS to PWM Decoder allows the use of any standard analogue or digital servos with an S.BUS compatible receiver.
S.BUS specific servos are therefore not required.
With 4 programmable channel outputs, assignment of each servo to a channel of choice can be acheived with only one input lead from the receiver.
Channel Outputs: 4 programmable
Channel Ouput Lead Lengths: 200mm
Overall Length: 350mm
Please note: The FrSky Servo Channel Changer is required (sold separately) to change assignment of channel outputs.

can i use two of the decoders on one receiver as i want to put one in each wing, would i have to use a y- lead or can i plug into two ports
im using the g-rxr 8 receiver
I don't think that that is possible!
Just saw this post, 2 decoders can be used off a Y lead into the SBUS port, I’ve done this on a warbird with 4 servos in each wing, so 1 decoder per wing half.
I think you would have to be mindful as to what current is going to be drawn!
I have Frsky X8R as receiver and Taranis X9Lite.
To communicate with dual Esc Flsky (PWM signals) Is strictly necessary to have a decoder to move from SBUS to PWM?
Yes it is.
I believe the maximum current rating is <6amp so you can easily add battery power from a Y-lead on the servo side.
Regarding the above comments the decoder translates sbus to pwm so to add additional chanels you simply Y-lead from Subus to two pwm modules giving you 8 additional channels etc. Just remember to program the respective channels prior along with the channel range on TX.
In the instructions the pwm lead outputs are 210mm, max 350mm. So important to add your required cable lengths from the sbus output first, as required.
I hope some Frsky technician gives us the recommended limitations for number of pwm devices and possible upgrade for the servo output lengths by adding an signal amplifier module?
