Power rating on GPIO pins
What is the max power (ma) that any one GPIO pin can source? What is the max combined power of all GPIO pins in output mode?
If this information is available somewhere, I can't find it.
You may also look at the esp32 data sheet, page 28:
and other documents at that site:
On the top is:
"Absolute max per pin is 12mA - recomended 6mA"
