1.3 inch SPI Serial Interface TFT Product Introduction
SPI to serial chip is a multifunctional chip that can convert SPI interface signals into serial signals, which can be used to connect external devices and achieve communication with them. SPI to serial port chips have the advantages of high-speed transmission, low power consumption, and ease of use, and can be used in application scenarios such as computer hardware, household appliances, and industrial control.
The 1.3-inch TFT LCD module works very well and successfully completes my DIY project. It has an SPI interface, Its IC Driver is ST7789, There are two display way: horizontal display and vertical display, we can adjust the display direction. You need to set SPI_MODE3 on init, Arduino Nano, VCC to 5V and BKL to 3.3V. If you also purchase this one, be sure to check out the links mentioned in the product description before using them and they will help you with your project.
This 1.3 inch SPI TFT LCD display is with a diagonal size of 1.3 inches and a resolution of 240x240. This module supports SPI interface, making it very convenient for users to program and use. It can operate within a temperature range of -20 ℃ to+70 ℃ and Its storage temperature range is -30 ℃ to+80 ℃.
