Hi guys, I am trying to connect my Arduino Uno R3 with esp-wroom-02 wifi module, however, the 3.3v source of UNO can only provide 50mA current, which is not enough to push esp-wroom-02 (operating current 80mA).
I would like to ask if it is possible to power the esp wroom 02 with the 5V source. (Any way I can reduce the 5v source to 3.3v? Or can I draw more than 50mA from the 3.3v source?)
Also, does it means that I do not need any resistor (or extremely small resistor) when connecting the 3.3v source with the esp-wroom-02 module since the maximum current is only 50mA?
