It supports both 4-bit and 8-bit parallel communication and can be interfaced with microcontrollers via direct GPIO or using an I2C backpack for simplified wiring. Ideal for menus, sensor readings, and status messages, it\u2019s a staple in embedded systems and IoT projects.<\/p>\n<p data-start=\"813\" data-end=\"831\"><strong data-start=\"813\"
