[ CABLE / ADAPTER RECORD // USB 2.0 STANDARD-A TO MICRO-B ]
USB 2.0 Type-A to Micro-B Cable
Type-A host to Micro-B device; D+/D−, VBUS and ground for USB 2.0.
CLASSIFICATION: Data, peripheral, and high-speed cables. Identify protocol, direction, pinout and exact cable revision before connection.
Interface and capability
| Standard / protocol | USB 2.0 Standard-A to Micro-B. Connector appearance alone does not establish compatibility. |
|---|---|
| Endpoint / pinout | Type-A host to Micro-B device; D+/D−, VBUS and ground for USB 2.0. |
| Capability / limits | High-Speed signaling is 480 Mbit/s; cable assembly length and charging current are separate product/USB requirements. |
| Certification / length | Standards define interface requirements, not every assembly’s performance. Certification, mode, current/power rating, direction and maximum length belong to the exact product/revision and complete channel; verify its manufacturer specification. Do not infer certification from connector shape or marketing terminology. |
Compatibility & handling
- Ensure device supports data, not charge-only. USB 3 Micro-B is wider and different; this cable does not imply USB-C PD.
- Inspect connector keying, latch, contact condition, shielding, jacket and model/revision marking. Stop if contacts are bent, loose, scorched, corroded or mismatched.
- Route without tension or sharp bends; follow product bend-radius, strain-relief, current and environmental limits. Test at the intended protocol and mode—physical fit is not a compatibility test.
