Package Included
- 1Pcs x 14 Segment 4 Digit 0.54 Inch For Arduino

Description:

- Working voltage: 5V (3.3V is relatively dark)
- IIC address: default address 0X70
- Digital tube size: 0.54 inch
- Display colour: Red

Pin Description:
- C: Serial clock line
- D: Serial data line
- -: Supply voltage-
- +: supply voltage +
- +: IIC level control terminal (connect 3.3V or 5V)
- A0, A1, A2,: IIC data address control terminal
- IIC address calculation: 0X70+A0+A1+A2 (floating is 0, welding A0 is 1, A1 is 2, A2 is 4, for example A0, A2 welding IIC address at this time = 0X70+1+4=0X75)
