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.
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.
