Hey folks,

I´m sure that you noticed the recent trend of displaying the RSSI signal on your camera image.
Nowadays there are many OSDs on the market displaying this signal.
But to use this feature you need to modify your rc receiver.

There are a lot of different RC receivers available. So it isn't easy to find the right pin to grab the RSSI signal.
Therefore I want to start to collect pictures of receivers (with marked RSSI pin) and wiring diagrams.

I know there are threads about this topic in different forums, but nowhere is a good overview.
With your help we can change this.

Soon, I'll add a new thread in Knowledge-Base each transmitter will be placed in a single post. So we can link on each receiver out of the first post.
To show you what I mean please visit our German forum. There we've started the collection today, too: RSSI-Pins - Overview (German forum)

Ok, let's start!

Schulze Alpha 8.35w
Schulze Alpha 8.40w (equivalent to version 8.35)

Chip: 31136
Pin 12

should i post here the same as in the german forum?

anyway:


i have 3 Futaba PCM receivers and all of them have the RSSI signal on the same place.

Futaba R148DP
Futaba R149DP
Futaba R1410DP

this photo is not from me, because i didn't make one, while i had the receivers opened:

It is the middle pin of the 3 connection pins, which join the two boards.

To use the RSSI signal without problems, i suggest to use a RSSI Buffer.
Here i made already a how to:

Hey, thanks for your picture!

I´ve created the RSSI-Pin - Overview in our Knowledge Base.

Please post your photos or data here, so we can add to our overview-thread!
With your help we will create the best rssi pin overview in world

Does anyone know if there is an RSSI pin inside the 2.4Ghz GP-707 A/V receiver? I have had a look inside and tested two promising looking pins with my multi-meter but did not have any luck.

Receiver: Futaba R136F
Chip: 31136
Pin: 12
The Resistor 100k was soldered and directly to the board and glued to the chip. The cable to OSD was soldered to it after.

Me too im looking for a GP707 rssi pin anyone ?

Hi guys,

who are willing to help me.
I started to fly with my Tricopter. Had some problems with interferences, and also some crashed. However last times I had successful flights for about 100-200meter at 15-20m altitude.
I want to go further but I am a little afraid. And for then I think maybe will be better to make RSSI pin for my reciver, and connect it to my E-OSD (HK).

I'm using Walkera 2801Pro TXRX. The receiver has diversity and uses ATMEGA88 as processor.

Can someone suggest where the RSSI pin can be? I guess it should be one of the ATMEGA pin-s, and have measured voltages on every pin. but there are too many pins which with variable voltage with TX on and off.
