**Type:** Product page · **SKU:** CE09992 · **Brand:** [Core Electronics](https://core-electronics.com.au/brands/core-electronics-australia)
**Page:** https://core-electronics.com.au/7-segment-display-red-breadboard-compatible-core-electronics.html ([markdown](https://core-electronics.com.au/7-segment-display-red-breadboard-compatible-core-electronics.html.md))

This is a breadboard-friendly 0.5" single-digit, 7-segment LED display with a common cathode configuration.

## Pricing

- **Price:** $1.00 (inc GST) — $0.91 AUD, exc GST

## Availability & dispatch

- Out of stock — the product page offers email notification when it returns.

## How to buy

- **Build a cart:** compose `https://core-electronics.com.au/cart/link?items=CE09992:1` (comma-separated SKU:qty pairs) and share the link. Opening it shows a confirmation page with live pricing and stock before anything is added to the cart.
- **Verify the cart first:** fetch `https://core-electronics.com.au/cart/link/CE09992:1.md` for live line prices (inc & exc GST, quantity discounts applied), stock and dispatch estimates, and totals. Append `/to/{AU-postcode}` (or `/to/{country-code}:{postcode}`) before `.md` for delivery options and prices to that destination. Unknown, retired, or out-of-stock SKUs are flagged. (Query form `cart/link.md?items=...` also works but some robots parsers refuse query strings here.)
- **Checkout** is completed on-site and includes a captcha at the payment step. Share the cart link; checkout takes it from there.
- **Search the catalogue:** `https://core-electronics.com.au/search/{query}.md` (URL-encode the query; pages 2-3 at `search/{query}/{page}.md`; `search.md?q=` also works)

## Description

This segment display is a breadboard-friendly 0.5" single-digit, 7-segment LED display with a **common cathode configuration**. Its compact design and straightforward operation make it perfect for electronics projects like clocks, counters, and timers. Thanks to its pin layout, it can be easily aligned across the center of a breadboard for multi-digit displays.

### Features:

- **Breadboard Friendly Design:**
    The pins are positioned along the top and bottom of the display, making it easy to place multiple units side by side across the centre section of a breadboard for seamless multi-digit displays.
- **Common Cathode Configuration:**
    Simplifies understanding and usage. When the logic output is **high (Vdd)**, the segment is **on**—making it more intuitive than common anode displays, which require a low (GND) signal to activate.
- **Compact Size:**
    Measuring **19mm long** (top to bottom), this display fits comfortably across the middle section of a breadboard, leaving two free pins on each side for easy wiring.
- **Low Forward Voltage:**
    With a forward voltage of **2V**, the display works smoothly with both **3.3V and 5V logic** levels when used with appropriate series resistors.
 
### Technical Specifications:

- **Display Type:** 7-segment, single digit
- **Digit Size:** 0.5 inch
- **Colour:** Red (Peak Emission: 633 nm)
- **Configuration:** Common Cathode
- **Forward Voltage:** 2.0V (Typical)
- **Max Continuous Current:** 20 mA per segment
- **Operating Temperature:** -20°C to 80°C
- **Dimensions:** 19mm height
