TM1637 4-digit 7-segment LED display

The display module has the simplest possible design and is based on the TM1637 driver with a two-wire bus interface. The TM1637 four-digit 7-segment display does not support the standard i2c protocol because the module does not have a slave address. Manufacturers offer display models with white, red, blue, and green LEDs; the seven-segment display measures 0.36 or 0.56 inches.
