cc-usage-elink shows Claude Code usage on a BLE tri-color e-ink display. It is built for the 蓝签 EDP-42000DDF display and gives you a simple way to check usage without opening another app.
This tool is useful if you want a small desk display that shows your Claude Code usage status in a clear format. It keeps the screen calm and easy to read.
Go to the Releases page to download and run this app on Windows.
On that page, look for the latest release and download the Windows file attached to it. If you see more than one file, choose the one made for Windows. After the file finishes downloading, open it to start the app.
Before you run cc-usage-elink, make sure you have:
For best results, keep the display close to your PC during setup. BLE devices can be harder to connect if the signal is weak.
Open the Releases page and download the latest Windows release.
After the file downloads, open it from your Downloads folder.
If Windows asks for permission, choose the option that lets the app run.
Turn on the 蓝签 EDP-42000DDF display and make sure it is ready for pairing.
If your PC does not see the display right away, move it closer and try again.
Run cc-usage-elink from the downloaded file. The app will try to connect to the display and send the usage data to it.
Once the app connects, the e-ink display should show Claude Code usage data in a clean layout.
After setup, using the app should be simple:
If you keep the app on your PC, you can update the display whenever you need to check your Claude Code usage.
This app is made for the 蓝签 EDP-42000DDF BLE tri-color e-ink display. It uses the display in a way that fits low-power desktop use.
Because e-ink screens refresh in a different way than normal monitors, you may see a short delay when the data changes. That is normal for this type of screen.
The release page may include one or more files. For Windows, choose the file meant for Windows. If the release includes a setup file, use that one first. If it includes a portable file, you can open it directly after download.
Use the Releases page any time you need the latest version.
This app is built for a simple purpose: show your Claude Code usage on a small desk display. It is not meant to replace Claude Code. It gives you a quick view of usage on a separate screen so you do not need to check it in another window.
If you use Claude Code often, this can help you keep track of usage while you work.
When you open the Releases page, the newest version is usually at the top. The file name may include words like:
Choose the file that matches Windows. If you are not sure which file to use, pick the one that looks like the main app download for your system.
Go to the Releases page, download the latest Windows build, and run it on your PC
