OPI Power from Header ?

[dhlii]

Can you power an Orange Pi Zero or Orange Pi One from the 26/40 pin header ?

I am pretty sure the answer is yes as the OPI Zero expansion board has a power jack. 

 

But is there any information regarding how to do this ?

 

Do you feed the +5v or the +3.3v Is it the same for all of the RPI compatible headers ?

The Answer is yes
Pin 2 or 4 for 5V and Pin 6 for GND

To find out where Pin 1 (Square) is - see the backside of the PCB - Pin 1 is a soldered square.

Thank you. 

 

The graphic is nice but I know where the power pins are. I just wanted to make sure that if I feed +5 to the 5V header - instead of drawing +5 from the 5V header that the OPI will be happy and run from it. 

 

Obviously I need to provide enough power. 

 

Thank You again

Yes that will work - did try that with my OPi One - where the Micro-USB port doesnt work anymore

Thanks, I eventually found confirmation of this on the Xulong web site. 

 

I am trying to make an IoT expansion board that the OPI0 plugs into,  and seek to power the OPI0 from the expansion board.

The original Opi Zero NAS expansion board does have a real power-connector (on the right) and some other goodies onboard
