3.3V source on the Intel Aero Compute Board

Hi all,

I am looking to make use of the 3.3V line that are present on the 80 pin connector.

I can either pull it out from the J1 Power Board connector, or the J2 Radio Control connector.

1. Would like to know if the both 3.3V lines on both connectors come from a common source (regulator).

2. If they are from the same source, how much current can it source?

3. If they are separate, how much current can each of them source?

Thanks in advance

Regards

Hi Hmlow,

 

 

Thanks for your patience.

 

 

I have been reviewing your questions with the development team in order to be able to answer them, and this is the information that we have: The 3.3 pins are connected to the 3.3V power rail which goes to a common source that is a single step-down regulator (RT7258GQW) from VBATT.

 

 

About the current, there is a 1.3A isolator between the power rail and the 3.3 pins on the I/O connector.

 

 

I hope this is the information that you were looking for.

 

 

Have a nice day.

 

 

Regards,
