This Driver board is ideal for hooking up your micro-controller projects to a 4", 5" or even 7" display panel with a resolution of up to 800x480. The RA8875 chip is a perfect match for your project, as it allows you to drive a large TFT screen, using a simple SPI interface, and it has 768KB of RAM for buffering and displaying any type of data/image you want. The hardware accelerated shape drawing of basic shapes allows you to build complex, high speed images, and the inbuilt English/European font is ideal for adding text the the image.
The RA8875 Driver board can also handle 4-wire resistive touchscreens, and this can be accessed over the SPI interface. There's also an IRQ pin that is triggered when a touch is detected.
