The PixelPal (or generic 1602) 16x2 LCD with an I2C interface features a 16-character, 2-line display. By utilizing an onboard PCF8574 I2C backpack, it reduces wiring to just four pins, freeing up valuable GPIO pins on your microcontroller for other sensors or modules.
📌 Hardware & Pinout
The display relies on a 2-wire serial interface (SDA and SCL) for communication.

🛠️ Contrast & Backlight
-
Contrast Adjustment: There is a small blue potentiometer (trimmer) on the I2C backpack. If you turn on your display and see nothing but boxes or a blank screen, use a small screwdriver to gently adjust this dial until the text becomes clear.
-
Backlight: Most models feature a blue background with white text. The module usually includes a jumper (often labeled LED) on the backpack—removing this jumper will disable the backlight to save power.
