FuriBee F90 Wasp SP F3 EVO pinout?
#1
Hi,

trying to get an FlySky PPM receiver to talk to the Wasp's FC. The original receiver was a DSMX receiver, but I don't have a compatible transmitter.

Connecting the wires on the same pins did not work, probably because the DSXM was powered by 3.3V, and the FlySky eats 5V.

The picture shows the FlySky receiver laying on top of the original DSMX one, with the DSMX one still wired to the FC. I found that the pin in between the black and the white wire is a regulated 5V pin, so I connected the red wire of the FlySky receiver there.


But alas, no luck. No receiver signal in Betaflight, also not with the IBUS protocol selected, but that was to be expected with a PPM receiver  Wink. And yes, I have PPM set to ON on my transmitter, and the binding process appears to have worked.

Should I perhaps wire the white wire to the pin next to the battery input wires? I do not measure anything on that pin, so that could be an input pin, right? Maybe for PPM?
Does anybody know the pinout for this particular board? It apperars to be brand-specific.

I Have a F90 Wasp and fly sky receiver
here's a link to gearbest at bottom of page
it shows the pin outs you need to solder
to RX2  5V and Ground  they are right
next to each other

Thank you jep4755! That was exactly the info I was looking for Smile


That at least means I have the wiring correct. So My trouble-shooting can focus on the transmittersettings, binding, and Betaflight, and the soldering iron can stay in it's case for a bit.
Unless of course, I have a faulty receiver... But I tried with a known-to-be-working IA6B as well, and that too did not give any response in Betaflight's receiver tab.

Looks like the same RX I have used to replace the one on my tiny7, but I can't say for certain?

This RX is AFHDS  not AFHDS 2A, go into 'System Setup' menu on the TX, down to 'RX Setup' and 'RF Standard' to change the AFHDS mode. Switching from AFHDS 2A (solid LED on RX) to AFHDS (flashing LED) should get your stick inputs recognized by BetaFlight. I know the flashing LED on the RX while bound confused me!

Note that this RX has no failsafe and is 6 channel, so only 2 switches can be assigned, I don't think AFHDS mode supports iBUS at all...?

Hope this helps?

Thanks, Tom!

I have seen the flashing light on the RX before, and dismissed that as "not bound", so there may be my error.
I have the TX set-up for AFHDS, and PPM only, indeed. But maybe I got the UART wrong in Betaflight. Been playing around with UART 2 and 3, and maybe I just skipped the correct combo of UART, AFHDS/PPM / AFHDS2/IBUS, and wiring. With the wiring sorted out, I'll try PPM on UART2 first, as that seems the most likely to succeed.

(have to get more time in a day, though. 24hrs is just not enough...)

Mmmhhhh.....

Now, I don't get the RX LED to blink. It just lights solid blue.
Press and hold the button, and power up. That should be the procedure to enter bind mode, but as soon as power is applied (through either USB or battery), the blue LED lights up solid, and remains on. Button pushed or not, makes no difference. No flashing whatsoever.
The transmitter, powered up in binding mode, does not recognise the receiver.
AFHDS selected (AFHDS2A "OFF").

I suspect the receiver is faulty...
