Description
Touch TFT LCD display with a diagonal of 3.2" and a resolution of 320 x 240 px with 65536 colors. Works with a voltage of 3.3 V and communicates using the SPI bus and parallel interface. It is equipped with ILI9325 controller - is responsible for the screen, and XPT2046 is responsible for the touch.
Leads are the holes with wsoldered goldpin connectors- 2.54 mm pitch. They allow the connection of the display via wires or attaching to the breadboard.
The manufacturer offers auser guide along withsample programs for FPGA and STM32. |
Leads
The screen has the following leads:
