7 mm 3-Digit 7-Segment Display, Common Anode (2831BS) — Red 🔴
The 2831BS is a compact 3-digit 7-segment LED display with a digit height of 0.28 inch (7 mm). Featuring a common anode configuration and ultra-bright red emission, it delivers high-contrast numeric indication for clocks, voltmeters, counters, and general-purpose instrumentation. A black face with white segments enhances readability, while the 2.54 mm pin pitch simplifies prototyping and panel integration.

Integration Notes 🛠️
- Use an appropriate current-limiting resistor for each segment.
- For multi-digit operation, drive via multiplexing and stay within the specified peak and average currents.
- With a common anode device, segments are typically driven by current-sinking outputs.
- Observe maximum ratings and soldering guidelines to ensure long-term reliability.
