## Summary description

Waveshare 4×8-segment red display module with SPI interface designed for use with Raspberry Pi Pico. The module provides four separate 8-segment numeric displays in a compact board form factor, controlled over SPI for easy integration into microcontroller projects. Typical use cases include numeric readouts, status indicators, clocks, counters and simple user interfaces in embedded applications.

## Long description

The Waveshare 4×8-segment red display module with SPI interface for Raspberry Pi Pico is a compact numeric display board that integrates four separate 8-segment red LED digits on a single module. Designed for direct connection to a Raspberry Pi Pico, the module uses an SPI serial interface to simplify wiring and minimise pin usage while providing clear numeric readouts and simple segment-based indicators. The physical form factor and pinout are intended for embedded projects where a small, readable numeric display is required.
Advantages
The module's SPI interface reduces required I/O lines compared with parallel-driven displays, facilitating easier integration with Raspberry Pi Pico and similar microcontrollers. Its red 8-segment LEDs offer high contrast for numeric and simple symbolic output while keeping power consumption relatively low. The compact board layout combines four digits in a single footprint, saving space on small enclosures and development boards and allowing straightforward mounting and wiring.
Suitable for
Numeric readouts for sensors, voltmeters or temperature displays
Simple status indicators and counters
Clock or timer displays in embedded devices
Basic user interfaces for consumer or industrial prototypes
Key specifications
Display format: four separate 8-segment digits
LED colour: red
Interface: SPI serial communication compatible with Raspberry Pi Pico
Mounting: compact PCB module suitable for panel or prototyping board installation
Control: segment-level control for numeric characters and simple symbols
How to use
Connect the module to the Raspberry Pi Pico using the SPI pins and the required power and ground lines according to the manufacturer's pinout. Use SPI-enabled libraries or write SPI routines on the Pico to transmit segment data to each digit; the module accepts serial data to update segments directly. Ensure voltage levels match the Pico's I/O levels and include current-limiting or drive settings as recommended to protect the LEDs. Initialize the interface in your firmware, then send per-digit segment patterns to display numbers, simple symbols, or scrolling values as needed.
Usage recommendations
Operate the display within the recommended supply voltage and current limits, avoid prolonged maximum brightness to extend LED life, and implement software debouncing and refresh routines to maintain stable readable output. For multi-digit numeric values, manage leading zeros in software and use brief blanking or separators to improve readability when displaying changing values.
