An 8-digit serial LED display module that uses an SPI (3-wire) interface, requiring only three I/O pins from your Arduino or microcontroller. Multiple modules can be daisy-chained together for longer displays. The flicker-free design ensures a clean, stable readout.
Key Features
- 8-Digit Display – Red 7-segment LED digits
- SPI Interface – Only 3 wires needed (data, clock, latch)
- Daisy-Chainable – Link two or more modules in series
- Flicker-Free – Stable, clean display output
- 5 V Operation
Specifications
- Power Supply: 5 V
- Digital Bits: 8
- LED Colour: Red
- Interface: SPI (3-wire)
- Dimensions: 122 × 20 × 12 mm
Ideal For
- Counters, clocks, and score displays
- Sensor data readouts
- Arduino and microcontroller projects needing numeric output
Package Contents
- 1× 8-Digit Serial LED Display Module
Resources
Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode is a small electronic component that lights up when current flows through it in the correct direction. In this kit, LEDs create the flashing effect, so polarity and correct soldering matter for the project to work.
- microcontroller
- A microcontroller is a small computer on a chip that runs your program and controls connected inputs and outputs. For this product, it is the part that reads buttons and sensors, drives the display and speaker, and communicates over Bluetooth.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
