ESP8266 wemos d1 mini 3.3V pin max amperage

[sentinel66]

Hello,

I am using ESP8266 wemos d1 mini and i want to power two relay boards with it. Its a 3V relay board (link below) and i measured and it draws 0.12A from 3.3V pin, so that would mean 0.24A draw for 2 relay boards. Is this safe ? How much can i safely draw from 3.3V pin ?

The voltage regulator on the Wemos D1 mini appears to be a ME6211.
According to a datasheet I found, its Iout = 500 mA.

Your ESP8266 draws current. Look at its datasheet.
Add to that the relay board 0.24A.
