1.3 inch LCD HAT

1.3” LCD HAT is a 1.3-inch diagonal display HAT with 240 x 240 resolution, 65K RGB colors, clear and colorful displaying effect, Four Push buttons and a joystick, designed for the Raspberry Pi to expand its engagement via SPI communication by providing a standard 40 pin GPIO interface. The 1.3" LCD HAT includes an integrated ST7789VM display driver and SPI interface, reducing the number of IO pins required. It features a 5-input joystick that is internally connected through a stackable GPIO connector header.
