Here we have a 4 Digit common cathode super bright (25-30mcd) LED display.
Each digit has 7 segments and a dot to the bottom right.
- 25 - 30 mcd brightness
- Red LED
- 7 Segment
- 4 Digit
- Common Cathode
- Dot to the right of each digit
- 0.56" Digit Height
- Easy PCB / breadboard mounting
- 1 x 4 Digit LED Display
Below you will find a circuit diagram for connecting this unit to an Arduino. Please be aware that the LED segments of this display require a current-limiting resistor when powered from a 5 V logic pin. The value of the resistor is typically between 330 and 560 ohms; the higher the value, the more the current that is limited, and the less bright the LED segments.
