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

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/AAAAAAAAAB0/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. -- For more options, visit http://beagleboard.org/discuss --- You received this message because you are subscribed to the Google Groups "BeagleBoard" group.
