The STM32U5G9J-DK2 Discovery kit embeds a 5-inch 800x480 TFT LCD MB1860 board, which is connected to
the RGB interface of the STM32U5G9ZJT6Q MCU through a 50-pin connector (CN3).
The MB1860 board uses the RK050HR18-CTG TFT LCD from Rocktech including a backlight and a capacitive
touch panel.
The touchscreen controller is connected to the STM32U5G9ZJT6Q MCU via the I2C2 bus, at the 0x5D address).
