Use with 3.3V or 5V logic ArduinosOnboard 3.3V @ 150mA LDO regulator2 white LED backlight£¬ transistor connected. Defaults to 'on' but can be connected to a digital pin for PWM or simply turning offDisplay current draw is mostly based on the backlight£¬ with full backlight the current draw is ~100mA£¬ this does not include the SD Card. SD cards can draw 20-100mA based on read/write. Measure current draw in circuit to get precise numbers.
