TM1638 Digital Display Development Board 24 Keyboard Scanning Display Control Module

Features: This module mainly treats the input unit as a separate module, reducing the burden on the main CPU. The module drives an 8-bit common cathode digital tube, scans 24 buttons, and assembles a STC15W microcontroller. With the power indicator, the running indicator of the MCU driver, the buzzer and the remaining two legs of the TM1638 drive the LEDs respectively. The M1638 chip hardware interface has been used. This module can meet the needs of the experiment, especially the early development of the product as a human-computer interaction panel, and the tuning/testing machine is very convenient.
