Hello,

I am pretty new here.

I need advice to select the best way to get information about the battery with telemetry link. I don't use flight controller. I have a power sensor which gives the energy, the capacity, the current and the voltage over 3.3V.

I want to see these informations on the telemetry screen of the taranis. What is the best way to achieve that and which modem do I need to send these informations to the remote ?

Thank you in advance

What receiver?

I use a Fr Sky RX4R receiver.

I want to know if I can convert the analog outputs of my sensor to Sbus input for the receiver with an arduino or something more simple ?

One more question, I don't know what is the weird S pin between the pin + and AUX2 ? And what protocol is used for AUX2 pin ?

Thank you

AR610 is a DSM (Spektrum or compatible) receiver, not FrSky.
Aux2 sounds like an FrSky thing however... so please clarify what you're using.

AR610 is a 6 channel Spektrum receiver. It has no Aux2.
Aux2 is Channel 7 in Spektrum/JR terminology. (T,A,E,R, Gear=ch5, Aux1=ch6,Aux2=ch7,Aux3=ch8 and are JR/spektrum channel outputs.)

For FrSky (in glittering generalities;-)
1. SBus is the channel information sent from the receivers to servos or flight controllers.
2. SPort is the sensors input to the receiver.
In order to have the FrSky transmitter work the Spektrum rf protocol you meed a MultiProtocol module.
What sensor do you have that provides current, voltage, energy...?
What transmitter are you using? Different FrSky transmitters have different form factors for the multiprotocol module.

OpenXVario/Sensor is an Adruino project on this forum that is used to interface various sensors to SPORT.

But the AR610 is not neither SBUS or SPORT compatible to my knowledge.

Sorry I completely made a mistake on the receiver it is a Fr Sky RX4R.

The sensor I use, has analogic output but it is homemade by my university.

On an RX4R Ain2 takes 0-3.3V and sends that down, but that's only one value.
OpenXsensor seems to be a good option for you to translate your analog values to digital smart port data.
