AJMRTC TM1638 integrated display module is built around the TM1638 LED drive IC. It integrates three functions: 8-bit common cathode 7-segment digital tube for numerical display, 8 independent status indicator LEDs, and 8 touch-style push buttons for key input. It communicates with the main controller through a 3-wire serial interface, occupying far fewer IO ports than parallel display schemes. You can adjust the display brightness programmatically and read key scanning signals easily. It works perfectly with AVR, Arduino, STM32, ESP32 and other mainstream microcontrollers. It is widely used for digital counters, parameter setting panels, industrial data readout, electronic clocks, score counters and student electronic experiment projects.
