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

Jargon buster
Plain-language definitions for the technical terms used above.
- LED
- A light-emitting diode (LED) is a small electronic component that emits light when current flows through it in the correct direction. Because it only conducts one way, its polarity matters, and a through-hole LED must be soldered the correct way around to light up.
- microcontroller
- A microcontroller is a small computer on a single chip that runs a stored program and controls connected inputs and outputs such as buttons, sensors, displays and communication interfaces. In a device built around one, it is the part that executes the code and coordinates the device's behaviour.
- 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.
