FAQ
Q: Can this be used with ESP32? A: Yes, but ESP32 cannot plug in directly. You need to connect via jumper wires to the 8-bit parallel bus interface.
Q: What to do if the screen has no display? A: Check if the power connection is correct, confirm that the LCD_RST pin is properly connected to the board’s reset pin, and ensure initialization code is executed correctly.
