These 7 Segment LED displays modules feature super bright red illumination with a low operating current of ~2mA. The modules are organised with common cathode (ground) pins, and require a limiting resistor for each segment. The module’s digit size is 13.2mm (0.5″) x 7.6 (0.3″) and includes a right-handed decimal point.
These high quality and high efficiency modules are manufactured by Kingbright, and are supplied in packs of 4.
Example limiting resistors: 2K2 (5V), 1K0 (3V3), 4K7 (12V).
