1.Description:
  It is a TM1638 button digital tube.The chip used in the module is TM1638,which integrates the common peripheral circuits of the above three single-chip microcomputers.The biggest feature is that it only needs to occupy three IO ports of the single-chip microcomputer to drive.The scanning display and key scanning do not require the intervention of the single-chip microcomputer.Only the relevant registers need to be read and written to send the display data.Or detect buttons to save MCU resources.

2.Feature:
  1).It has 8 LEDs,and the working status can be seen through the LED lights.
  2).It has an 8-digit digital tube and a common cathode LED digital tube;
  3).It can be directly connected with STC and other microcontrollers.
  4).It has 8 buttons for easy operation,and the buttons are sensitive and display good results.
  5).It supports the provision of ardiuno-compatible drivers.
