Max current from a GPIO pin?

Postby Scalpel78 » Sat Mar 18, 2017 11:04 pm

Hi, this is probably one of the most basic questions here, but how much current can one GPIO pin supply on the ESP-WROOM-32?

Same as ESP8266 :

Imax = 12mA

Doesn't this depend on configurable drive strength? I don't think this is well documented anywhere.

Thanks for the reply. 12mA is not a lot, so I'll include a transistor to drive my two leds.
