Hi, I just want to ask about proper connection for Pico with OLED SSD1306 and Mosfet in VCC line for OLED.
I want to save more current on the battery, yesterday I left OLED connected to PICO and li-po battery, OLED was cleared, and today battery is empty, thought to use Mosfet to steering VCC supply line for OLED, but what I noticed is when I put (in my case B4) gate pin to 0 (digitalWrite(B4,0)) 0r (analogWrite(B4,0)) then my OLED still works. Screen isn't blank.
any advice how to switch this Mosfet off to cut off current for OLED?
I use IRFZ44N Mosfet
