How much current does this draw?

Backlight power consumption (typical) : 15mA Supply voltage (typical value) : 3.3V, 5V Module operating current (Max) : 1500uA (Vdd=5V),1250uA (Vdd=3.3V)

Is this random access, i.e. send row/col position and character pairs? Or does it just scroll?

I am using it with a ESP32. To display I send row number,column position with lcd.setCursor(0,0); Rows are 0-3 and columns are 0-19. Does not scroll.

Has anyone used these with a 3.3 volt device like a Raspberry Pi, ARM-based Arduino, or ESP32? How did you wire the backlight?

i used the sketch from printables on 3 an 5 volts to turn on and off back light i used a momentary button
