Difficultly showing the corresponding the data by the LED dot matrix of micro：bit control board, we particularly produce keyestudio micro bit 4-digit Tube Shield to highly enhance the digital display.
This shield mainly drives the TM1637 chip through the micro: bit board to control the 4-bit common anode digital tube. P0 is connected to CLK, and P1 goes to DIO. The micro bit control board is easily fixed on the shield with 5 M3*6MM flat screws if you use it.
