📷🔌 Nikon UC‑E12 USB Cable Family
 
(USB 2.0 • Proprietary Mini Connector • COOLPIX Compatible • USB‑only & USB+AV Variants)

The UC‑E12 family of cables connects select Nikon COOLPIX cameras to a computer for image transfer and, in some models, to a TV for composite A/V playback. Both versions share the same Nikon proprietary mini connector on the camera side, but differ in their host‑side breakouts.

🛠️ Quick Tips for Beginners
