🧠🔌 USB A • Micro USB B 2.0 Cable

This cable connects a USB Type-A host (like a computer or charger) to a Micro USB B device. It’s widely used for charging and data transfer in older smartphones, tablets, controllers, and embedded modules.
 
🔧 Cable Format & Use Case
🔌 USB Type-A Male → Micro USB B Male
USB-A plugs into host (PC, charger, hub)
Micro USB B plugs into device (phone, camera, controller)
Supports charging + data sync at USB 2.0 speeds (up to 480 Mbps)
 
🖥️ Compatible Devices
📱 Android phones (pre-USB-C era: Galaxy S7, Moto G, Nexus 5)
🎮 Game controllers (PS4, Xbox One, Amazon Fire TV)
📷 Digital cameras, GPS units, MP3 players
🔌 Power banks, Bluetooth speakers, e-readers (Kindle, etc.)

🧪 Debug or configure USB-powered modules
 
🧠 Signal Format Notes
⚙️ USB 2.0 standard—480 Mbps max transfer rate
🔌 Micro USB B has 5 pins: VBUS, D-, D+, ID, GND
🔋 Supports up to 2.4A charging (depends on cable quality)
🔄 Plug-and-play—no drivers needed for most devices
🚫 No video or audio passthrough—data + power only
 
⚠️ Things to Watch Out For
🚫 Micro USB B ≠ Mini USB—don’t confuse the shapes
🧯 Fragile connector—avoid stress or bending at the Micro USB end
📉 Slower than USB 3.0 or USB-C—limited for large file transfers
🔌 Some cables are charge-only—check for data support
🧪 Not reversible—orientation matters when plugging in
 
🛠️ Quick Tips for Beginners
🧠 Identify Micro USB B by its trapezoidal shape with beveled top
🔄 Always plug USB-A into host, Micro B into device
🧼 Clean ports gently—lint buildup can block charging
🏷️ Label clearly—Micro USB is still common in niche gear
🔋 Use short, high-quality cables for best charging performance
