1.3 inch IPS TFT LCD Display ST7789


This is a 1.3 inch display screen with a resolution of 240 (RGB) x240. It is an IPS full view LCD display panel so the color looks great in any direction. The drive IC is ST7789, and the universal 7-pin SPI interface is used.

The bottom has an SD card slot, which makes it easy to load full-color bitmaps from the MicroSD card in FAT16/FAT32 format.

Support the main control MCU such as ESP32/ESP8266/Arduino/STM32.
