Package Includes
- 1 × 16×2 LCD Display Module
Note: The display requires a 10kΩ potentiometer (or equivalent) connected to the V0 (contrast) pin for optimal character visibility. It operates from a 5V DC supply and is fully compatible with the LiquidCrystal library in Arduino IDE. For projects with limited GPIO pins, an I²C LCD adapter (sold separately) can be used to reduce the interface to just 4 connections (VCC, GND, SDA, and SCL).
