1602 LCD USB Mini Drive Board, RPI Driver Free (ATmega8A)

Mini USB driver board for 1602 LCD displays, based on the LCD2USB project and featuring an ATmega8A microcontroller. It allows connecting a standard 16x2 LCD via a micro-USB port without requiring drivers on Raspberry Pi systems.

The board comes preflashed with LCD2USB firmware using VUSB technology. It frees up GPIO pins on the Raspberry Pi and includes two detectable input buttons (key-a, key-b) plus a serial UART debug port for advanced use cases.
