This compact microadapter converts a USB Type-A port into a USB-C socket, letting you connect USB-C cables to older computers, laptops, and hubs that only have USB-A ports.
The adapter supports USB 1.1 and USB 2.0 data transfer (no USB 3.0 pins). It provides standard 5 V power at up to 1 A — note that USB-C power delivery negotiation is not supported since the host port lacks that capability.

- Reversible USB-C Socket – No orientation required on the cable side
- USB 2.0 Compatible – Supports data transfer up to 480 Mbps
- Compact Form Factor – Minimal size, easy to carry
Ideal For
- Connecting USB-C development boards to older computers
- Using USB-C cables with legacy USB-A ports

Jargon buster
Plain-language definitions for the technical terms used above.
- USB 1.1
- USB 1.1 is an older USB standard with much slower data transfer than USB 2.0 and later versions. Compatibility with it allows connection to very old computers, though data-heavy tasks such as video may be limited at that speed.
- USB 2.0
- USB 2.0 is a widely used wired standard for carrying both data and power between a device and a computer or other compatible host, with data rates up to 480 Mbps. It indicates the kind of port a device uses and that it should work with most modern and many older computers.
- USB-C
- USB-C is a small, reversible USB connector that can carry power, data and, on some devices, video over a single cable. The same connector can range from charging only to high-speed data, so the functions a given port actually supports vary.
