RE: [beagleboard] Maximum current on pins

[Gerald Coley]

It is found in the processor datashhet. It isn't much. 6mA max and as low as 
3mA.

Subject: [beagleboard] Maximum current on pins

Hello,

how do I figure out, how much current I can source/sink from my BeagleBone 
Black's pins? What I have found:
The manual of the AM335x Sitara Processor 
(http://www.ti.com/product/AM3359/technicaldocuments) provides me with a table 
of the pin attributes.
The following pictures show the pin configuration of my BeagleBone Black.

[cid:image001.jpg@01D2D53E.6A387820][https://lh3.googleusercontent.com/-br4zU6dpRn8/WSbWd2-x6-I/AB0/A66cMQyc_3EUIkvH6LtG3Y6uaw5mLUJdQCLcB/s1600/P8_Header.png]
For example: I want to know the maximum current I can source from P9_11. Then I 
would look for the signal "GPIO_30".
The table tells me its provided by the processor pin named "GPCM_CSn1" which 
can provide 6 mA.

Is my answer correct?

However, I can't find "SYS_5V" for example. How much current can I source from 
that pin? And where do I get the information from?

I would be grateful for your help.
