I did have a quantity of the BlueJayF7 (the precursor to the NERO) made and tested using the 746. It is a huge chip, as you can see.

I have right now in my hands a f767ZIT6, its a 2MB flash one, on LQFP144 : thats a square of side 2cm. I belive it should fit in our 36mm FC without problem?
BGA, less user serviceable? Who will come and tinker solder made in reflow oven, I don't get it.
Was the f746 on the bluejay f7 the reason why you skipped to Nero?


One more, unrelated, concern : is there a huge capacitor on the back to accomodate direct 6S power? Can add an extra no problem, just to know.

Any idea when these will ship?

Wanted to do another build soon.

I am having fun with the BlueJay F4 rev3 while waiting for my Neros, it sure flies great!

Is it 500ma max of the nero F7 onboard polulu to get 5v from vbat lipo?

Did you see that....

It'll be whatever the Pololu will deliver. We will be releasing a 2A piggy back board shortly.

You don't need a pololu to get vbat. You can just connect vbat to the 3-6s input.

Hi Jason.

Can the nero handle more then 5V input such as 7V or 9V input? Then you could directly connect most Vtx that require 7V+ directly to the output, instead of having a 5V and 12V pdb like most people have. I assume the micro, sdcard is already stepped down to 3.3V. If everything else you have connected on the "5V" line could handle more then 5V then you should be OK? The x4r/xsr can handle up to 10V it looks like.

Yes, it can handle up to a 6S LiPo directly. It just doesn't have a Vreg to power your auxiliaries. Instead it has a region on the board to safely nestle any pololu regulator your heart desires, which is actually much better than an internal Vreg imo. Much much better actually.

Yes the LDOs for 3v3 are rated for input above 12v. So technically yes if you want to run yours at 7-9v it'd work fine.

It'll be about 2 weeks after. I've yet to finalise the design on the mini.

That is great news
Will you also allow preorders for the mini?
