USB LCD Displays
176x220 2" Full Color TFT LCD
Part Number: CFAF176220U-020T
This 2" TFT screen can power up to 262K colors using 8-bit 8080 parallel, or down to 4k color. This module has an integrated Sitronix ST7775R controller.
The backlight on this display only requires 3.3v, making this a great choice for a screen in applications where high voltage requirements pose a problem.
Note that this display uses a solder down tail- designed to be soldered directly to corresponding pads on a PCB using a hot-bar soldering machine. This means the connection is both ultrathin and very low-cost. However, it also means this display may not be the optimal choice for hobbyists. Instead, we'd recommend a module with a ZIF tail.
