TM1637 4-Digit & MAX7219 8-Digit 7-Segment LED Display Module — 0.36 Inch, Red, Clock Anode Tube
This listing covers both the TM1637 4-digit 7-segment LED display module and the MAX7219 8-digit 7-segment LED display module — the two most popular 7-segment display solutions for Arduino, ESP32, and microcontroller projects. Both modules display numbers, letters, and symbols with bright red 0.36-inch LED digits, and both are supported by extensive Arduino libraries for quick integration.
The TM1637 uses a simple 2-wire interface (CLK + DIO) and is ideal for clock, timer, and counter displays. The MAX7219 uses a 3-wire SPI interface and supports up to 8 digits, making it the choice for longer numeric displays and cascaded multi-module setups.
TM1637 4-Digit Module
- 4-digit 7-segment display — ideal for clock, timer, and 4-digit counter displays
- 2-wire interface (CLK + DIO) — minimal GPIO usage; easy Arduino integration
- Colon separator — built-in colon for clock time display (HH:MM)
- Adjustable brightness — 8 brightness levels via software
MAX7219 8-Digit Module
- 8-digit 7-segment display — ideal for longer numeric displays and cascaded setups
- 3-wire SPI interface (DIN, CS, CLK) — daisy-chainable for more digits
- Adjustable brightness — software-controlled via SPI
- Socketed digit tubes — replaceable digit tubes for long-term serviceability
