KS0483 Keyestudio Micro bit 4-Digit Tube Shield(Black and Eco-friendly)



Description

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. The four-digit tube module is a 3.6 inches common anode digital tube, and the display color is red.

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.
