WWZMDiB 4 Digit 7 Segment Display Board
These 4-digit modules use the TM1637 driver IC, enabling control of four 8-segment LEDs with just two signal lines. They support decimal and letter displays and operate at 3.3V to 5V with a typical current range of 30–80 mA, making them versatile for hobby and education projects. This multi-pack is helpful for experimenting with cascaded displays or teaching basic digital timing concepts.
HiLetgo 4-Digit TM1637 Display Module
This 0.36-inch red common-anode display uses the TM1637 driver and includes four LED digits with adjustable brightness. It features four M2 screw holes for straightforward mounting, a clock point, and a clear colon-like separator. This is a compact option ideal for time displays or compact readouts in small projects and installations.
DIYables 4-Digit 7-Segment With Colon
These modules offer two 4-digit TM1637 displays with a colon in the middle, enhancing readability for time formats such as hh:mm or mm:ss. The package includes two displays, and the colon serves as a programmable visual separator. They are suitable for hobby clocks, timers, and simple display dashboards, with straightforward 2-wire control via the TM1637 protocol.
Lonely Binary 6X Color TM1637 Display Kit
This kit includes six color options (yellow, green, blue, white, orange, red) 0.56-inch four-digit displays with a central colon. It emphasizes easy TM1637 integration using two GPIO pins and common libraries, making it ideal for beginners building color-coded clocks, timers, or dashboards. Expansion is feasible by sharing the CLK line across multiple displays.
Lonely Binary 6-Pack 0.56″ TM1637 Displays
This pack provides six 0.56-inch four-digit TM1637 displays with decimal points for easy time or numeric readouts. The kit supports simple wiring and is designed for scalable projects such as multi-digit clocks, counters, or dashboards. Its color options enable quick visual differentiation among multiple displays in a single project.
diymore TM1637 5 Colors 0.56″ Displays
This set includes five color options (red, green, white, yellow, blue) for 0.56-inch TM1637 displays. The modules are designed for easy plug-and-play use with two-wire digital IO, and the 8-level grayscale capability offers flexibility in display brightness and contrast for varied projects.
Buying Guide: Key Considerations For 4-Digit TM1637 Displays
- Display size and readability: 0.36″ versus 0.56″ digits affect visibility at a distance and in compact enclosures. Larger digits are easier to read but take more space.
- Driver and interface: TM1637 is common for simple two-wire control. Ensure your microcontroller supports the library you plan to use and check pin requirements.
- Color options and readability: Colored digits or multi-color kits can improve readability in multi-display projects or when color-coding information.
- Colon and decimal points: Colon separators are useful for time displays (hh:mm); decimal points expand display capabilities for other data formats.
- Power supply: Many modules operate at 3.3–5V. Verify voltage compatibility with your MCU and any additional components to avoid overcurrent issues.
- Mounting and enclosure: Some kits include enclosures and mounting holes. Consider how you will attach the display in your project box or chassis.
- Expandability: If you need multiple digits, look for chainable designs or modules that share control lines efficiently without excessive wiring.
- Documentation and libraries: Availability of sample code and community support speeds up development. Look for modules with clear instructions and examples.
- Durability and build: Plastic housings and robust connectors help in educational settings or hobby labs where modules are handled frequently.
