Max ratings for the BBB outputs...

alamorobotics
alamorobotics over 11 years ago

Howdy...

 

I'm trying to make sense of the Datasheet for the AM3359 and it seem to me the GPIO is limited to 6ma (some even 4ma) each and 100ma total (on VDDSHV6).

So it seem to me that I should really buffer the I/O and not drive an LED straight from a GPIO pin...

 

Am I reading the Datasheet properly ?

    I don't disagree, leds with suitable resistors will be fine. However, for comparison, page 6 of the BBB schematics has this for the onboard leds.

    Guess it's a personal preference, but I love the blue LEDs. And I do remember the whole search for the Blue LEDs. It really is amazing how much brighter with less current the "modern" LEDs are, compare…

    And I do remember the whole search for the Blue LEDs.

     

    It really is amazing how much brighter with less current the "modern" LEDs are, compare to the ones in the 80-90s...

    And I guess they are only going to get brighter in the future...image

    I've never had the LEDs on SBCs cast shadows throughout the house at night before.

     

    Those blue LEDs on BBB really are awesome. image
