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:

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.

    Macro photographs of the cable connector and receptacle that clearly show the pins would be helpful. (Count the pins. Go to a store, and ask to try some cables.) – xiota Sep 19 '19 at 3:20

    Have you asked Panasonic? – mattdm Sep 19 '19 at 4:05

    @mattdm While in general a good idea, I would bet quite a bit of money that their answer would include some corp-speak like "Panasonic is determined to deliver the best user experience. As such, we cannot comment on whether or not third party cables work on our camera. Third party equipment might damage your equipment, in which case your warranty is void." That's the answer I always got from manufacturers (though I never had contact eith Pana) – flolilo Sep 19 '19 at 10:50

It's the same cable as for my DMC-FZ200 and a whole wagonload of older and newer Panasonic models. Quite a number of third-party sources for cheap variants. It's definitely not compatible with any standard USB connector and may have been around before micro-USB was standardized. Also the socket contains pins for video I think. Here are photographs of socket (the right one in the photograph is USB/AV, the left being HDMI) and plug:HDMI and USB/AV sockets of Panasonic Lumix DMC-FZ200 Panasonic USB plug So bite the bullet and get one. They are comparatively cheap and ubiquitous. Usually it's more convenient to just swap the SDcard though. With the FZ200, the corresponding flap is so close to the tripod mount that you cannot do so without unmounting the camera. The solution I finally adapted was using a lens clamp for holding the camera on the tripod. That way, the SDcard flap stays accessible. It may well be that the GM5 does not have a similarly absurd SDcard access position but I thought I'd mention it just in case.


Go to Amazon and enter "Lumix DMC-GM5 USB". You will see what they sell for that, which is a pin-out known as UC-E6.

However... this is a USB-2 cable, which means your photo transfers will only go at USB-2 speeds. With a USB-3 card reader, you can read the SD cards as SD cards speeds which is about twice as fast.

  • Unfortunately my new Macbook Pro lacks an SD card reader. USB C only. – Simon Woodside Sep 19 '19 at 19:15
  • There are USB-C card readers. – xenoid Sep 19 '19 at 20:34

The cable is --- non-USB UC-E6

  • What are the differences? Are they physical, electrical or both? – Philip Kendall Sep 19 '19 at 10:44
