The 1 Digit 7 Segment 0.56 Inch Red LED Display is a single-digit red LED display component with seven individual LED segments (labeled a through g) arranged in a figure-8 pattern, plus one decimal point segment — allowing the display to show any single digit from 0 to 9 and a limited set of letters by turning on the correct combination of segments through direct GPIO control from an Arduino, ESP32, or any microcontroller. Unlike the TM1637 four-digit module that has a driver IC handling all segment control through a two-wire interface, this 1 digit 7 segment display has no onboard driver IC and connects its eight individual segment pins plus two common cathode pins directly to the microcontroller or breadboard, making it the fundamental learning component.
The common cathode 7 segment display has 10 DIP pins in a through-hole package — five pins on each side — that insert directly into a standard breadboard for rapid prototyping without soldering. The 7 segment display arduino connection requires one GPIO pin per segment with a current-limiting resistor on each, or the outputs of a 74HC595 shift register to reduce the GPIO count to three pins for the full eight-segment control. The 19×13×7mm physical dimension makes the 0.56 inch red led display easy to place in custom PCB layouts and project panel cutouts. This 7 segment display price-accessible component is ideal for Arduino, ESP32 single digit readout counter STEM project and breadboard 7-segment learning display.
