I am not seeing any clear answer for the source current that the GPIO pins can provide. I think I have already broken the PWM pins on my AGX Orin by drawing too much current, but I was only trying to toggle an simple LED (mA range current). I have looked through multiple data sheets though and am having no luck. I am turning to this forum to try to get and answer for 1 - max current draw for GPIO pins (specifically the pwm ones) 2 - if any other pins can provide a pwm signal besides for gpio433/GPIO27/pin15 and gpio391/GPIO35/pin18 since those seem to have been broken from drawing too much current.
Hi, for GPIO pins, the max output current is about 2mA.
Does anyone have any suggestions on how to buffer the pins or add a little more current capacity to them? I’m trying to trigger cameras and the max current is not high enough for the cameras to register the trigger signal. I read in another thread someone connected the GPIO to an arduino input, then did an ISR to turn an output high/low. That could be ok but it’s obviously clunky and not super scalable. Thanks in advance!
