+This configuration sets up the NuttShell (NSH) interface over USB Serial (refer to the usbserial
+configuration for details). It also enables I2C1 and the driver for an alphanumeric/segment LCD.
+Specifically, the setup supports a 16x2 LCD screen based on the HD44780 controller, which is
+interfaced using an I2C adapter known as the LCD Backpack, utilizing the PCF8574 chip.
