The module is typically a charging connector flex / PCB board which includes the charging port (USB type / micro USB depending on variant) mounted on it.
It replaces a broken or damaged port assembly (if the original connector is worn out or has bent pins).
Often labeled as “Original / OEM replacement” in listings, and they emphasize precise machining and matching dimensions for the Note 3 model.
Some listings note that “Image shown is for presentation purpose only; actual product may differ.”
The flex includes solder pads and traces to connect to the mainboard; also mounting holes or alignment tabs.
