UCOM-IR USB AVR Programmer and IR Communication (COM3) Driver

The UCOM-IR USB AVR Programmer and IR Communication (COM3) driver helps Windows recognize Nicai’s USB device so compatible software can access its AVR programming and infrared communication functions. It is intended for users setting up the programmer for the first time, reconnecting it to a different computer, or troubleshooting a missing serial-port connection.

Key Features

• Device recognition: Enables Windows to identify the UCOM-IR hardware and make it available to compatible programming and communication applications.
• Serial-port access: Supports access through an assigned COM port. Although the device name includes COM3, Windows may assign a different port number depending on your system.
• Programming and IR connectivity: Provides the driver connection needed by compatible tools to use the device’s AVR programming and infrared capabilities; separate application software may still be required.
• Windows compatibility: Listed supported systems include Windows 10, 8.1, 7, Vista, and XP. Choose a package appropriate for your Windows version and architecture, where separate options are available.

How to Install UCOM-IR USB AVR Programmer and IR Communication (COM3) Driver

1. Check your system. Confirm your Windows version and whether it is 32-bit or 64-bit. If you are looking for Windows 10/11 compatibility, note that Windows 10 is listed as supported, while Windows 11 support is not confirmed here.
2. Select the correct package. Before starting the UCOM-IR USB AVR Programmer and IR Communication (COM3) driver download for Windows, verify that the package identifies Nicai’s UCOM-IR device and supports your operating system. For any free download, check the source and accompanying installation notes.
3. Prepare the files. Extract the archive if necessary. Follow any included instructions about whether to connect the programmer before or after running setup.
4. Install the driver. Run the supplied installer, if included. For a manual installation, open Device Manager, locate the connected device, select Update driver, and browse to the extracted driver folder.
5. Verify the connection. Check Device Manager for warning icons and note the assigned COM port. Select that port in your compatible AVR programming or IR communication software, then test the connection.

Keep your driver package and setup instructions available for future reinstalls. Before you update, compare the installed driver with the latest version offered by a trusted source and review its compatibility notes. A newer release may address connection issues, but it should explicitly support your device and Windows version.
