Hello! I have recently started sourcing parts of a Ambika build. I’ve been having trouble sourcing a proper HD44780 compatible 40x2 OLED screen. I bought a AL4002A (not cheap!) from midiphy, without checking to see if it was 5v or 3.3v It’s rated for 3.3v. Is there any way to modify this part in the Ambika build? I am comfortable with SMD rework
I just noticed there is a 3v/5v jumper here. I wonder if that is all there is to it? Wish I could find more information like a schematic online.
