This blue LED module is a four-digit alphanumeric display designed for projects that need to show more than just numbers. With 14 segments per digit, it can present letters, numbers and symbols, plus a decimal point on each digit.
It uses a common-anode configuration and includes four 14-segment digits. The LEDs have a maximum forward voltage of 3.6V and a continuous forward current of 20mA.
It is a good fit for custom indicators, instrument panels, clocks and other embedded builds where a compact character display is needed.
Jargon buster
Plain-language definitions for the technical terms used above.
- common-anode
- A wiring arrangement where several LEDs or LED segments share a common positive (anode) terminal and are switched individually on their negative (cathode) side. Common-anode and common-cathode parts, such as RGB LEDs, seven-segment displays, matrices and strips, are not interchangeable without a suitable driver.
- continuous forward current
- The amount of current a diode can carry in its normal conducting direction for an extended time without overheating. This rating helps you choose a diode that can safely handle the load in your circuit.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
