The company provides Arduino/PlatformIO samples for the T-RGB on GitHub, including a factory test program and some LVGL library samples. I can also a sample to use the 2.8-inch display with the ESP-IDF 5.0 framework. At this time, there are three T-RGB models: two with a 2.1-inch display, and the new one with a 2.8-inch display.
