Hi everyone,

I posted earlier about my Cinelog35 FC getting fried after a hard landing.

I just ordered a new GEPRC GEP-F722-45A AIO for replacement:

https://geprc.com/product/geprc-gep-f722-45a-aio/


After ordering, I noticed in the specs it says "Dshot600,Oneshot,Multishot" compatible.

But my new Cinelog35 was set for Dshot300 from the factory.

Not sure why the replacement doesn't mention Dshot300 when from the factory that is what it was set to in Betaflight when brand new.

Is this cause for concern?

With this new direct OEM replacement FC coming in a week or two, should I just load the original CLI settings including the original Dshot300 specs?

Or will I need to change stuff for the new board? If so, what kinds of things will I need to change?

I've watched some videos but still not clear on the difference between Dshot600 and Dshot300.

Could somebody please explain to a noobie?

Thanks in advance!

The "Dshot600" specification is the maximum DSHOT speed the ESCs support. Your FC will also support the lower Dshot300 and Dshot150 speed protocols. DSHOT300 is often used when bi-directional DSHOT is switched on (for RPM filtering) because it reduces the CPU load on the MCU compared to DSHOT600 and most pilots who aren't top racers will never notice the difference between the different DSHOT speeds. I used to run DSHOT1200 when older Betaflight versions supported the 1200 speed, but I now run DSHOT300 and I honestly can't tell the difference.

As long as the new FC is the same as the original one and you run the same same minor Betaflight version on it then you can just simply restore the CLI settings from your original FC.

You might also want to have a watch of this...

I really appreciate the explanation, makes sense and much appreciated.

Now I'm sweating over learning to solder before my first FC transplant arrives....ohhhhh the horror!

Have a Happy New Year brother!

I appreciate the link, very interesting!

So, sounds like a setting that would NOT have an adverse hardware effect? 

Premature burnouts or anything if configged incorrectly in relation to the FC specs?

It's just different (speed efficiencies) communications protocols between the FC and ESCs?

No, you won't damage anything by simply just changing the ESC protocol. Each of the protocol selections is just a different language / speed that the FC uses to talk to the ESC.

Happy New Year
