Description
Product Overview
The uxcell 10‑pin common cathode 2‑bit red 7‑segment LED display tube is engineered for reliability and ease of integration in a wide range of electronic applications. Measuring just 0.35 inches in height with a panel size of 15 × 14 mm, the module fits comfortably into tight spaces while delivering a luminous intensity of 11 mcd, which is bright enough to be clearly visible under typical indoor lighting conditions. Constructed from a durable plastic housing and metal pins, the display is designed to withstand repeated handling and soldering processes. Each LED segment operates at a forward voltage of approximately 2 V and a forward current of 20 mA, resulting in a modest power consumption of 36 mW per unit. The package includes five identical tubes, allowing developers to create multi‑digit displays or replace faulty units without delay. The common cathode configuration simplifies wiring for microcontroller‑driven multiplexing, making it a popular choice for hobbyists and professional engineers alike.
Usage
These red 7‑segment LED tubes are versatile enough to be employed in a variety of environments. In home appliances, they can serve as clear numeric readouts for temperature settings, timer counters, or weight indicators on kitchen scales. Instrument panels in automotive or industrial equipment benefit from the compact footprint and low voltage requirements, enabling designers to display status codes or error numbers without adding bulk. For educational purposes, the modules provide an excellent hands‑on learning tool for students exploring digital electronics, binary counting, and multiplexing techniques. DIY enthusiasts often incorporate the tubes into custom clock projects, scoreboards for tabletop games, or decorative lighting installations where a retro‑style numeric display is desired. Because the tubes operate efficiently at low current, they are also suitable for battery‑powered devices, extending operational life while maintaining visual clarity.

FAQ
What voltage should I use to drive the LED display?
The display is designed to operate at a forward voltage of around 2 V per segment. For best results, use a constant‑current driver rather than a constant‑voltage source to maintain uniform brightness across all segments.
Can I connect multiple displays together for a larger numeric readout?
Yes, the common cathode design makes it straightforward to cascade several modules. By using a multiplexing circuit or a dedicated driver IC, you can control up to four or more digits with minimal additional wiring.
Is the red color suitable for outdoor use?
While the red LED provides good contrast indoors, outdoor applications may require additional protection against moisture and UV exposure. Enclosing the display in a sealed housing will help maintain performance in harsh environments.
What is the recommended method for soldering the pins?
Standard lead‑free solder with a temperature of 260 °C works well. Apply a small amount of flux to the pins before soldering to ensure a clean joint and prevent oxidation.
Do you offer any warranty or after‑sales service?
All uxcell products come with a one‑year limited warranty covering manufacturing defects. Our support team is ready to assist with any technical issues or replacement requests during this period.
