4 Bits TM1637 LED Display Module & Clock 7 segment display module

The 4 Bits TM1637 LED Display Module is a 4-digit 7-segment LED display with a centre colon, driven by the TM1637 chip. Only two data wires, CLK and DIO, are needed to show numbers, time or simple text, which leaves the rest of your Arduino or ESP32 pins free. The colon makes it ideal for clocks, timers and counters.

4 Bits TM1637 LED Display Module Specifications

• Driver IC: TM1637
• Digits: 4, 7-segment, with a centre colon for clock display
• Interface: 2-wire serial (CLK and DIO), not standard I2C
• Supply voltage: 3.3–5 V
• Brightness: 8 levels, set in software
• Pins: CLK, DIO, VCC, GND

4 Bits TM1637 LED Display Module Applications

• Digital clocks with an RTC module such as the DS3231
• Countdown timers and stopwatches
• Temperature and sensor readouts
• Scoreboards, counters and simple menu displays
• Arduino and ESP32 classroom projects

What's in the Box

• 1 × TM1637 4-digit 7-segment display module

Tip: Install the TM1637Display library in the Arduino IDE, connect CLK and DIO to any two digital pins, and use showNumberDecEx() to switch the colon on for a clock display. Lower the brightness in software to reduce current draw when running from a battery.
