Special Features

  • 【Massive 4" Jumbo Size Visibility】 Extra-large 100mm+ character height for easy reading from afar – ideal for scoreboards, large clocks, timers, counters, temperature displays, or event signage
  • 【Integrated Driver PCB Simplifies 12V Drive】 Custom back board handles high-voltage 12V segments while accepting 3.3V or 5V MCU logic – just connect power (12V + 5V/3.3V) and send serial data
  • 【Chainable Click-On Design】Modules snap together effortlessly – daisy-chain multiple units using only 3 GPIO pins (data, clock, latch) for multi-digit displays without extra wiring hassle
  • 【Plug-and-Play Convenience】No complex transistor arrays or high-current drivers needed – perfect for Arduino, ESP32-S3, Raspberry Pi Pico, STM32, and other microcontrollers
  • 【Easy Coding & Tutorials】Simple serial interface with provided GitHub code examples, libraries, and step-by-step tutorials for quick setup and custom projects
  • 【COMPLETE 2-PACK KIT】 Includes 2 Jumbo 4-inch (100mm) 7-segment LED display modules with built-in 74HC595 driver and 1 male pin header strip for connection. Controller board and wiring accessories not included. Build large displays for scoreboards, clocks, counters, and dashboards.
