About this product
A 4-digit 7-segment LED display with 0.56-inch digits in a common cathode arrangement, emitting red light at a dominant wavelength of 660 nm. It is used for showing numbers in counters, clocks, meters and Arduino projects. The display operates from -40 °C to +80 °C and can be driven through a 74HC595 shift register to reduce the number of pins needed.
