Qian Yuan Technology Click the blue text Follow us LED displays are composed of arranged light-emitting diodes. They use low-voltage scanning drive, featuring low power consumption, long lifespan, low cost, high brightness, few failures, wide viewing angles, and long visibility distance. Compared to LCD displays, LEDs have advantages in brightness, power consumption, viewing angle, and … Read more
Introduction to Digital Tubes A digital tube is a type of semiconductor light-emitting device, with its basic unit being a light-emitting diode. Digital tubes are categorized into seven-segment and eight-segment types, with the eight-segment tube having an additional light-emitting diode unit (for displaying a decimal point). The connection method for light-emitting diode units is divided … Read more
The DB25 serial port generally only uses three pins: 2 (RXD), 3 (TXD), and 7 (GND). With the continuous improvement of devices, the DB25 connector is rarely seen today, and it has been replaced by the DB9 interface. The pins used in DB9 differ from those in DB25, specifically 2 (RXD), 3 (TXD), and 5 … Read more
