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.
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.
Parameters
- Working voltage: DC 3.3V
- Working current: 50mA
- Maximum power: 200mA
- Working temperature: -20 ℃ --60 ℃
- Size: 52 * 52 * 10mm
- Weight: 15.4g
- Environmental attributes: ROHS
Connection Diagram
Test Code
Install the library file successfully, click the 8 TM1637 to set the corresponding test program.
Test Result
After uploading the code successfully, wire according to connection diagram (power is supplied to the micro: bit control board, and the power supply method can be freely selected). After power-on, the LED dot matrix on the micro: bit control board displays a heart-shaped pattern, and a 4-digit digital tube displays number “1234”
