Lcd I2C - Overview

LCD I2C adapter​

This LCD I2C Adapter simplifies the connection between your LCD display and any Arduino-compatible board, such as Dasduino. Utilizing I2C communication, it only requires two pins for operation, making setup quick and straightforward.

Our LCD I2C displays come with the adapter soldered on, which enables characters to be displayed on the LCD screen via the I2C bus.

With our provided library, you can get started in just a few minutes. Plus, with Qwiic (formerly easyC) connectivity, no soldering is required, making the process even more convenient!
