Add letters, numbers and symbols to your project with this green 14-segment alphanumeric LED display. Compared with a standard seven-segment display, the extra segments make it much easier to show readable characters as well as numerals.
The display uses a common-anode configuration and provides four 14-segment digits, with a decimal point available for each digit. It is suited to compact readouts, status panels, clocks, counters and other maker projects where a simple text or numeric display is needed.
Each LED segment has a maximum forward voltage of 3.6V and a continuous forward current of 20mA, so choose suitable current-limiting resistors or a compatible LED driver for your circuit.
Features:
- Green display
- Four 14-segment digits
- One decimal point per digit
- Displays numbers, characters and symbols
- Common-anode display
Specifications:
- Polarity: Common Anode
- Dimensions: 40mm x 11.95mm
- Max forward voltage: 3.6V
- Continuous forward current: 20mA
Jargon buster
Plain-language definitions for the technical terms used above.
- common-anode
- A wiring style for multi-colour LEDs where the positive side is shared and each colour channel is controlled on the negative side. This matters because common-anode and common-cathode LED strips are not interchangeable without a suitable driver.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- LED driver
- An LED driver is a control chip or circuit that supplies and switches power to LEDs. For a display board, it reduces the number of microcontroller pins needed and handles tasks like lighting the right segments and adjusting brightness.
- Seven-segment display
- A common numeric display made from seven LED bars arranged to form digits. It is good for numbers but limited for letters, so comparing it with a fourteen-segment display helps you judge what kind of text the product can show.
