4 inch SPI Serial Interface TFT Module Product Introduction
Model No.: SFTM400XM-7173AT
SFTM400XM-7173AT is a 4 inch LCD module adopting a 4-wire SPI
communication method, with a driver IC of ILI9488, a resolution of
480x320, and touch function (optional). This module includes an LCD
display screen, backlight control circuit, and touch screen control
circuit.
- 4.0-inch color screen,support 65K color display,display rich
colors, 480X320 resolution, with touch function.
- Using the SPI serial bus, it only takes a few IOs to illuminate the
display.
- Eeasy to expand the experiment with SD card slot and touch pen.
- Compatible with Arduino R3/Nano/Mega controller boards, which will
improve your project operation.
- Provide a rich sample program and underlying driver technical
support.

Hardware Configuration
The hardware circuit of this LCD module consists of three main
parts: LCD display control circuit, touch screen control circuit,
and backlight control circuit.
1, The LCD display control circuit is used to control the pins of
the LCD, including control pins and data transmission pins.
2, The touch screen control circuit can control the touch screen
touch response and touch coordinate reading (touch screen
optional).
3, The backlight control circuit is used to control the backlight
brightness and dimming. Of course, if backlight control is not
required, this circuit can be omitted and the backlight control pin
can be directly connected to a 3.3V power supply.
