4-Inch 7-Segment LED Display, 74HC595, 2-Pack

Two jumbo 4-inch single-digit seven-segment displays with a 74HC595 driver board on the back, so a microcontroller can run 12 V segments from 3.3 V or 5 V logic.

Highlights

• Readable at a distance. 4-inch digits for scoreboards, timers and wall clocks.
• Driver built in. The back board switches the 12 V segments, with no transistor arrays to build.
• Chainable. Daisy-chain modules for multi-digit displays on the same data, clock and latch lines.
• Sample code. Examples on Lonely Binary's GitHub.

In the box

• 2 × 4-inch single-digit display module, each with the 74HC595 driver board on the back
• Male pin header strip, to cut down for the IN and OUT rows
• Female sockets in two sizes, 5-way for the signal row and 2-way for the 12 V row

Specifications

• Digit height: 4 inch
• Segment supply: 12 V, separate supply (not included)
• Logic supply: 3.3 or 5 V
• Wires to your board: 5, including GND
• Driver: 74HC595

Works with

Arduino, ESP32, ESP32-S3, Raspberry Pi Pico, STM32 and other microcontrollers. A controller board and 12 V supply are not included.
