LED S564
0.56" 4-Digit 7-Segment Display
- Overview
- Commands
- Samples
- On-Module Code
A 4-digit 7-segment display at 0.56" digit height — the largest in the 4-digit family. Available as a counter with decimal point or a timer with colon, in red or green. Drive it with simple text commands over any supported interface; segment timing and digit multiplexing are handled on the module.

Common uses: gym timers, scoreboards, public display counters, kitchen-timer builds, and any project where the digits need to read from a distance.
For smaller digits, see LED S284 (0.28") or LED S404 (0.40").

Modules ship without cables to reduce waste. Some specialty boards include a USB cable; for the rest, see Cables to add cables to your order.
Commands this module accepts. See Samples for runnable code in popular host languages.
| Function | Description |
|---|---|
Init() | Initialize the module. Automatically called on power up. |
Digit(n) | Draw n number to LEDs. |
Seg7(i, s) | Draw a single s digit (0 to 9) on i digit. |
Dot(i, v) | Draw a dot at i index with v value (0 off 1 on) on count-type LED. |
Colon(n) | Show colon on time-type LED. |
DVer() | This driver version. |
Peek under the hood
The script below is this module's driver — it teaches the hardware how to respond to the commands listed above. It ships pre-loaded from the factory; most users never need to open it.

This sample runs in MicroBlocks on a any host board that's connected/tethered to this module, or a chain of modules. This module keeps its official DUELink firmware and module driver and responds to commands from the connected MicroBlocks-running host. New here? See the MicroBlocks page.
There are two ways to use it:
Open the full sample — the complete project (the module's library plus a ready-to-run example) opens directly on the MicroBlocks website.
Add just the libraries to your own project — copy the link, then in your MicroBlocks project click Add Library → Cloud and paste it. This loads this module's libraries into your project without replacing your current work.
Copy Library LinkCode that runs directly on this module's MCU. See how On-Module Code allows modules to run standalone.
- Script
This example runs using the default DUELink Internal Engine using its Scripting Language, and it expects the module's driver to be loaded first, see the Commands Tab.
