keyestudio 4-digit LED Display Module TM1637 for Arduino

This 4-digit LED display module is a compact, easy-to-use 7-segment display powered by the TM1637 driver chip. It is perfect for students, makers, and hobbyists looking to add clear numerical readouts to their Arduino projects without complex wiring.

Efficient TM1637 driver chip

The module integrates a 0.36-inch 4-digit, 7-segment common anode display driven by the TM1637 chip. This setup simplifies the control interface, allowing you to display numbers and basic characters with minimal programming.

Reduced microcontroller wiring

By using a dedicated signal interface, this module vastly reduces the number of I/O pins required on your microcontroller. You can control the entire 4-digit display using only a few control pins instead of complex, multi-wire multiplexing.

Simple pitch header pins

Featuring four control pins with a standard 2.54mm pitch, the module connects directly to your microcontroller using standard jumper wires. This eliminates breadboard clutter and speeds up prototyping.

Convenient physical mounting

The board includes two 3mm fixed mounting holes, making it easy to secure onto chassis, custom enclosures, or robot bodies. This ensures your display remains stable and securely positioned during operation.

Compact and robust design

Operating on a 5V DC supply, this lightweight 7.2g module measures just 45mm by 21mm by 10mm. It is built to perform reliably across a wide temperature range from -40 to +85 degrees Celsius.
