Product parameters

Working voltage: 5V (3.3V is relatively dark)

1IC address: default address 0X70

Nixie tube size: 0.54 inches

Pin Description

C: Serial clock line

D: Serial data line

-: Supply voltage negative

+: Positive level of supply voltage

+: IIC level control terminal (connected to 3.3V or 5V)

A0, A1, A2: IIC data address control terminal

1IC address calculation: 0X70+A0+A1+A2 (suspended is 0, welding A0 is 1,

A1 is 2, A2 is 4, for example, A0, IIC address at A2 welding=0X70+1

+4=0X75 )
