The LED displays are electronic devices capable of displaying the numeric digits 0 to 9, and some alphabetic letters and graphic symbols, through the lighting of combinations of seven light segments consist of LED diodes, connected suitably between them in such a way as to reduce the number of connections to the output.
This module consists of one display and allows you to view 4-digit and 4 decimal points. Driven by a driver on board the PCB, the TM1637 saves resources and number of connections to the processor that will pilot thanks to 4-wire connection with I2C serial protocol (MCU, Arduino and other development kit). It can be used to display, for example in a digital instrument, the measurement of an electrical quantity, the date, time and other information represented.
Communication protocol: serial I2C
Digit size: 0.56"
Viewing Angle: 30 °
Display thickness: 8mm
Dimensions: 43 x 24 x 10h mm
