2.8 inch Capacitive Touchscreen Round TFT Moudle Description
This product has the characteristic of low input voltage, VDD: 2.7~3.6V. Due to the use of IPS technology, the product has an 80 degree viewing angle from any direction. The product uses RGB 18BIT values as the CPU interface and is equipped with an internal power circuit. This product is designed with a capacitive touch screen (CTP), which is more convenient to use and provides users with a very good experience.
