Leo found The Cricket at a surplus electronics bin in Shinjuku. The packaging was yellowed, the Japanese text boasting “4 MBPS FIR” — Fast Infrared. Four megabits per second. A laughable crawl now, but back then, it was a fire hose.

Effective communication range is approximately 1 meter (3.3 feet) with a 30-degree cone of transmission.

Connecting to older printers equipped with infrared interfaces. Where to Buy & Support

Fully compliant with USB 2.0 specifications (backward compatible with USB 1.1). It draws direct bus power from the USB port, requiring zero external power supplies.

The is not a consumer gadget. It is a specialized tool for a niche but persistent need. If you are trying to resurrect a 1998 Palm Pilot, service a 2005 medical infusion pump, or flash firmware to an embedded IR port, this is the only affordable, compact, and reliable solution on the market. | Specification | Detail | |---------------|---------| | |

While newer wireless technologies like Bluetooth and Wi-Fi have largely replaced consumer infrared, the U2IrDA Mini remains essential for specific professional and legacy applications. IrDA Tutorial - ACTiSYS Corporation

However, the U2IrDA Mini is far from obsolete. In industrial, medical, and engineering sectors, infrared ports remain standard on many legacy pieces of equipment—such as utility meters, medical diagnostic tools, and industrial printers. Technicians

Often includes a flexible extension cable to help align the infrared sensor with fixed-position devices like dive computers or industrial meters. User Feedback Pros: A laughable crawl now, but back then, it was a fire hose

When you connect the dongle to a Windows, Linux, or macOS host, the operating system typically recognizes it as a . Legacy IrDA stacks (like Microsoft's native IrDA driver deprecated after Windows 7) or third-party tools (like IrCOMM2k) can then bind to this COM port, enabling file transfers, printer connections, or modem emulation.

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