My Panasonic LUMIX DMC-GM5 comes with an unusual data connector for transferring photos to the computer. The manual identifies the part as USB connection Cable DMW-USBC1. When I look that up, the official Panasonic page doesn't provide any additional information about the connector.
Through research, it looks very similar to a USB Mini-B connector. For example:
- This related question indicates it's the same as "UC-E6"
- A site called Pinout Guide says "This plug used in many digital cameras. Often called 8 pin mini-usb, but not standard" and indicates that UC-E6 is the same or related
- Monoprice sells a cable that indicates it will be compatible and says USB Mini-B
- This Belkin Mini-B cable on Amazon has a number of reviews that say they are using it to connect to cameras.
If it's the same connector (i.e. USB Mini-B) with the same pins then that will make it easy to replace it or get a new one that connects to USB-C.
Update: I don't have a good macro so here are the best images I can get of the connectors.
