Gravity: I2C LCD1602 Arduino LCD Display Module (Blue)

The Gravity: I2C LCD1602 Arduino LCD Display Module is a 16-character by 2-line blue backlit screen designed for straightforward data visualisation. It is ideal for students, educators, and hobbyists looking to add text readouts to microcontroller projects without complex wiring.

Gravity I2C interface

This module uses standard I2C communication via a dedicated Gravity port, eliminating the need for bulky pin headers and drastically reducing required microcontroller I/O pins.

Dual 3.3V and 5V compatibility

Operating across a voltage range of 3.3V to 5.0V with an operating current under 20mA, this display integrates easily with both 3.3V and 5V logic controllers.

Optimised contrast and controllable backlight

Contrast adjustment is handled automatically without manual potentiometer trimming, while the crisp blue backlight retains full programmatic on/off control.

Clear 16x2 character layout

The screen presents 16 characters across 2 rows, providing clear alphanumeric readouts for sensor metrics, system statuses, and project debugging.

Wide environmental tolerance

Engineered for reliable performance in varied environments, the unit functions across an operating temperature range of -20°C to +70°C and stores safely between -30°C and +80°C.

Compact form factor and accessories

Measuring 87.0 x 32.0 x 13.0 mm, the module comes supplied with a compatible Gravity I2C/UART sensor cable for immediate plug-and-play wiring.
