{{ :sensor:tm1637_2.png?200|TM1637 7-segment display}}

The TM1637 module or chip is a driver for 4-digit 7-segment display modules. These chips are standard in inexpensive display units. They communicate with the processor using an I²C-like protocol. The implementation relies entirely on software emulation and does not utilize any specialized hardware, except for GPIO pins. It is assumed that pull-up resistors are present, typically integrated into the display module.


  * Operating voltage: 3.3 – 5 V DC
  * Maximum current draw: 80mA
  * Reverse polarity protection: Yes
