2030CRG-ARG Shu Shu patch digital pipe 0.2 inches three digital

2030CRG-ARG Shu Shu patch digital pipe patch 0.2 inches three digital tube 1. Product name: 2030CR-G 2, word bits: 3 3, light colors: red; (other colors can be customized) 4, pole : the common cathode / common anode 5, the surface color: gray panel, black panel 6, font color: red / green / blue / white / orange Product Description digital tube is actually composed of seven-eight light-emitting tubes constituted, plus a decimal point eight. These segments respectively, by the letters a, b, c, d, e, f, g, dp expressed. When a particular segment LED voltage is applied, these particular segments will light up to form two 8 digital words of our eyes to see the tube. Such as: display a "2", then it should be a bright light b e g bright bright bright f d c does not light does not shine bright dp. LED digital tube have generally bright and super bright different points, there are 0.5 inch, 1 inch different sizes. Strokes small size digital tube display common one light emitting diode, and large-size digital tube is made of two or more light emitting diodes, under normal circumstances, a single light emitting diode voltage drop is about 1.8V, current does not exceed 30mA. The anode is connected to the light-emitting diode is connected to the positive supply together is called a total of Yang digital tube, light emitting diode cathode connected to the negative power supply connected together referred to as common cathode LED. Numbers and characters commonly used in LED digital display is 0,1,2,3,4,5,6,7,8,9, A, B, C, D, E, F. LED digital tube characterization ★ ★ can drive the light-emitting light emitting at a low voltage, low current conditions are very short response time (
