Hosyond 3pcs IIC I2C 2004 LCD Module 20x04 LCD Screen Module Display for Arduino Raspberry Pi

How much current does this draw?

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