Specifications:
1.8" diagonal LCD TFT displayPhysical dimensions: 2.71" (69mm) width, 2.1" (53.5mm) height, 0.27" (6.94mm) thickness (top of joystick)128x160 resolution, 18-bit (262, 144) colorST7735R (datasheet) controller with built in pixel-addressable video RAM buffer4 wire SPI digital interfaceBuilt-in microSD slot - uses 2 more digital lines5V compatible! 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.
