Key Features

【24-DIGIT COMPLETE DISPLAY KIT】Includes 12 common cathode and 12 common anode 0.56" single-digit 7-segment LED displays — 24 digits total for clocks, counters, timers, scoreboards, and sensor readouts.
【12 PRE-BUILT 74HC595 DRIVER BOARDS WITH INTEGRATED RESISTORS】Pre-assembled 74HC595 shift register modules remove the need for individual current-limiting resistors, reducing wiring and simplifying breadboard prototyping. Each board is breadboard-ready.
【CONTROL MULTIPLE DIGITS WITH JUST 3 PINS】Daisy-chain shift register boards to drive multiple digits using only 3 microcontroller pins (Data, Clock, Latch). Build 4-digit clocks, 6-digit timers, or larger scoreboards without exhausting GPIO. Compatible with Arduino's shiftOut() function.
【24 SNAP-FIT 3D-PRINTED ENCLOSURES INCLUDED】Every digit comes with a matching 3D-printed snap-on case for a finished look while protecting the LED display.
【WIDE PLATFORM COMPATIBILITY】Works with Arduino Uno/Nano/Mega, ESP32, ESP32-S3, ESP8266, Raspberry Pi Pico, and STM32. 5V logic supports digits 0–9, letters A–F, decimal points, and custom segment patterns — for clocks, voltmeters, frequency counters, timers, scoreboards, and instrumentation panels.
【Compatible with Popular Microcontrollers 】– Compatible with Arduino IDE, ESP32-S3, Raspberry Pi Pico, STM32 and other development boards, making it suitable for prototyping digital displays, counters, and instrumentation systems.
