Fermion: Interface LCD Display Module

SKU: DFR0529

This is a 2.2” TFT LCD Display Module with an input voltage of 3.3V~5.5V, which is used to display colorful patterns and characters. The fastest screen refresh speed is about 256ms. The module is able to display multiple patterns in a cycle and realize dynamic display effect. At present, there are 19 common defined colors in the library, and users can also customize16-bit color codes. If we take the central point of the display as the origin of coordinates, the maximum absolute value of the positive and negative semi-axes will be 64.
