Gravity: 4-Digital LED Segment Display Module (Red)

The Gravity: 4-Digital LED Segment Display Module (Red) provides a clear 4-digit, 8-segment readout for showing numbers, sensor values, and status counters. Featuring standard I2C communication and plug-and-play Gravity compatibility, it is ideal for students, hobbyists, and makers building microcontroller-based instruments and clocks.

Clear 4-digit red display

The module uses an 8-segment by 4-digit red LED digital tube measuring 5.05 cm by 1.9 cm. It delivers sharp numerical readouts suitable for clocks, timers, and sensor monitoring.

Adjustable 8-level brightness

Integrated control allows you to select between 8 levels of display brightness. This enables you to easily adapt the screen visibility to indoor, dim, or brightly lit environments.

Standard I2C Gravity interface

Communicating over standard I2C, the module minimises pin usage on your development board. It is fully compatible with standard Gravity setups and operates at DC 5V.

Compact and robust design

Built on a 6.7 cm by 2.2 cm PCB, the board fits easily into tight project enclosures. It features an operating temperature range of -40 deg C to +85 deg C and includes an included Gravity 4-pin I2C connector cable.
