Description

Digital Tube LED Display Module 1/2/3/4 Digit 7 Segment For Arduino Raspberry PI
Product Information:
The digital tube can be divided into seven-segment digital tube and eight-segment digital tube according to the number of segments. The eight-segment digital tube has one more LED unit than the seven-segment digital tube, that is, one more decimal point (DP). This decimal point can represent the digital tube more accurately. The content to be displayed; according to how many (8) can be displayed, it can be divided into 1-digit, 2-digit, 3-digit, 4-digit, 5-digit, 6-digit, 7-digit and other digital tubes.
According to the connection mode of the light-emitting diode unit, it can be divided into a common anode digital tube and a common cathode digital tube. Common anode digital tube refers to the digital tube that connects the anodes of all light-emitting diodes together to form a common anode (COM). The common anode digital tube should connect the common pole COM to +5V in application. When the cathode of a certain field of light-emitting diodes When it is low level, the corresponding field is lit, and when the cathode of a certain field is high level, the corresponding field is not lit. Common cathode nixie tube refers to the nixie tube that connects the cathodes of all light-emitting diodes together to form a common cathode (COM). When common cathode nixie tubes are used, the common pole COM should be connected to the ground line GND. When a field of light-emitting diodes When the anode of a certain field is at a high level, the corresponding field is lit, and when the anode of a certain field is at a low level, the corresponding field is not lit.
