7-Segment Display - 20mm (Blue)

For ages, we've only had tiny or gigantic 7-segment displays. Now, here's a perfect middle - ground option. These 20mm 4 - digit 7 - segment blue displays are large enough to be clearly seen from afar, yet not so large that it's hard to find an enclosure for them. They are common - cathode displays with 4 x 7 - segment digits and a decimal point for each digit. The LEDs have a 1.9VDC forward voltage and a 20mA max forward current. Dimensions are 71.6 x 25.7mm. A datasheet is available for more details.

Using this 20mm blue 7 - segment display is easy. First, make sure to connect it properly according to the common - cathode design. When powering it, keep the forward voltage at 1.9VDC and don't exceed the 20mA max forward current to avoid damaging the LEDs. You can use it in various projects where long - distance viewing is needed. As for maintenance, keep it clean and dry. Avoid exposing it to extreme temperatures or humidity. If you have any technical questions, refer to the provided datasheet.
