Power supply considerations for Jetson Nano Developer Kit

[nicovernio]

@dusty_nv

The devkit may also be powered from pins 2+4 (pin 6+9 GND) of the J48 Expansion Header - up to up to 5V⎓3A per pin (5V⎓6A total).

Hi everyone! Could someone please clarify this? J48 is the power select, only 2 pins… I read somewhere else that:

@dusty_nv

Yes that is correct, you can supply up to 6A total through the 40-pin expansion header…

J40 is 8 pins… so if 2+4 would do, what would be 6+9GND?
Then… most importantly. I am actually having a B01 Jetson Nano. J40 doesn’t exist… would that be J50?
I really don’t want to blow up my board. Could you please indicate exactly which header/pins should be used?

Thanks in advance!

Hi dusty
in your original post
“The devkit may also be powered from pins 2+4 (pin 6 GND) of the J48 Expansion Header - up to up to 5V⎓3A per pin (5V⎓6A total).”

I think it should be J41, not J48 for addition power supply.

That would make sense, and works the same for A02 or B01. Still… better confirm?
