Serial Interface Board For 1602 LCD Display – I2C/SPI

Description

The I2C/SPI Serial Interface Board is a compact adapter backpack designed to simplify connecting a 1602 LCD to microcontrollers like Arduino, Raspberry Pi, or ESP32. It reduces a complex 16-pin parallel connection down to just 4 wires (VCC, GND, SDA, SCL). [1, 2, 3, 4, 5]

Key Features

• Pin Saver: Frees up valuable GPIO pins on your microcontroller.
• Built-in Potentiometer: Allows for quick, manual LCD contrast adjustment.
• Backlight Control: Includes a jumper to easily enable or disable the display backlight.
• Configurable Addressing: Features solder pads to change the I2C address, allowing multiple displays on a single bus. [1, 2, 3, 4, 5]
