MB1315 TFT LCD board

MB1315 is the TFT LCD daughterboard supporting RGB mode, available to mount on the
STM32L4R9I-EVAL board via CN1 connector.
The 4.3" TFT LCD uses LCD RK043FN48H-CT672B with a capacitive touch panel which only
supports 3.3 V power and interface. So a level shifter SN74LVC16T245DGGR is requested on
TFT RGB LCD daughterboard to support a wide power supply range.
