Hey, the “ Mamba F405 Mini MK3 DJI connection diagram” has an error that’s since been corrected (where the GPS serial is connected inline with the CRSF nano) – it might be good to swap that out or pull it? Seems people are finding it, it just showed up in the TBS Lounge again. Thank you so much!

Thanks for the heads up! The diagram was is partially correct, you just can’t use GPS and TBS CRSF Nano simultaneously. Didn’t find the corrected one so made an edit to the diagram.

But, why 405? Just to make something “affordable”/low price for something that doesn’t require high performance? Aka long range quads? I doubt F405 is good for 3” quads as they are very agile and require fast processing time.

F405 are powerful enough for any quad. KISS (V1) runs perfectly on the F3 MCU. But yes, the future is in F7/H7 MCU.

Bought 405 mk 3.5 30 amp stack . XM+ Reciever binds but no response to the controller .

You should connect the XM+ SBUS wire to the pad marked RC. Then it is all the matter of settings in the Betaflight Configurator. Use UART1 as Serial receiver input. Also don’t forget to set receiver to the “Serial based receiver” and “SBUS” in the Configuration tab.
