I assume this is the new 4 in 1 Suitable for the F12E? Without Ram swap requirement.

Is their another source. Amazon link says does not ship to Australia.

All of a sudden my Devo 10 with 4-in-1 module developed problems.
The range is only about 4 to 5 feet. I did not change anything in hardware and software configuration.
Does this mean the 4-in-1 module is gone, or can it also be another hardware or software problem.
I already checked connecting a different antenna direct to the 4-in-1 module, this has no effect.

Most likely you damage RF power amplifier at 4in1 module. It can be damaged if transmitter powered on without connected antenna.

I was thinking that too, but antenne was never off with the transmitter on....

If you have white Devo 10 with detachable antenna, I think it has UFL connector at small PCB inside antenna holder. That UFL connector can lost contact with antenna, I had such case with Devo 8s.

I have indeed a white Devo10, is there an easy way to check that connector?
Otherwise I might replace the 4-in-1 and immediately have the same problem...

You can check resistance between RF module UFL connector and output Antenna connector, for both ground and both center contarts.

Do you mean the connector on the wire that is going to the antenna? If yes, both ground and center are zero at both ends, meaning they should be OK.
Is it also possible to check resistance with UFL connector connected to the 4-in-1 board? For ground that should be no problem because I think the shielding on the board is grounded, but is there a connector point on the 4-in-1 that is directly connected to the antenna signal?

Checked, looks OK too...
What to do next, replace 4-in-1 module?

I'm afraid I'm not expert enough to do that.
Is there a way to check that is the problem or can there be no other reason to cause these problems.
I still don't understand what can have happened, since al antenna connections seem to be OK now.

I replaced the 4-in-1 module completely and now my Devo 10 is working OK again.
I'm not happy because I don't know what caused this, all measurements on the antenna were OK.

Is there something I can examine or repair on the defect module?

Sorry, nothing really important, I had thought someone made an universal RF using an esp32, but I was wrong.

Replied by devoflyer on topic F7 Adding an RF Module
Been searching around on the site but cant find anything definitive for the F7.

Picture of F7 Board with NRF24L01 (U.FL Antenna) on right.

Attachment not found



Can anyone confirm what the pins get connected to.
From what I've read it connects to A13, A14 and A15 for the Multi module.
I only need one of these but don't know where it is on the board.

NRF24L01 (U.FL Antenna)

Attachment not found


4 in 1 Module (for pin identification)

Attachment not found



On the Module I can see i need to connect,
From NRF24L01 to existing RF Module.
3.3V and CE to VN
Mosi to Mosi
Miso to Miso
Gnd to Gnd
Sck to Sck

I'm assuming CSN goes to either A13, A14 or A15 (dont know where they are).
I'm unsure where to connect IRQ from the NRF24L01

Any and all help is apreciated.
