Typically 1 centimeter to 1 meter at a 30-degree angle.

Why would you need an infrared adapter today? You'd be surprised how much equipment still relies on it: IrDA-USB Adapter инфракрасный порт Espada

The is a highly specialized hardware bridge designed to add Fast Infrared (FIR) communication capabilities to modern computers via a standard USB port. While consumer technology has shifted toward Bluetooth and Wi-Fi, the IrDA (Infrared Data Association) standard remains critical for industrial diagnostics, legacy data syncing, utility meter programming, and medical equipment calibrations. I need to gather information about this specific

The most persistent issue with the U2IrDA Mini has been finding functional drivers for modern operating systems. Official driver support extended only to Windows XP. However, the community has found several workarounds.

Works with MIR (1.152 Mbps) and SIR (115.2 Kbps). Interface: USB 2.0 (Plug-and-Play compliant).

As of 2026, Windows 10 IoT Enterprise LTSC 2021 still includes the legacy IrDA stack (disabled but present). However, Windows 12’s rumored removal of all 32-bit driver support could kill this dongle on Microsoft platforms forever. That said, Linux’s commit to legacy hardware and the retro computing community’s dedication mean this dongle will remain usable for at least another decade. Industrial users will simply dedicate a Windows 7 thin client to the task.
