EW-SD50 x EW-SD300 Electric Wire Adapter
Non-series components EW-AD305
It is about 31mm long and 8mm in width / diameter.
Use with the 12-speed Di2 and SM-PCE02
If you want to update the firmware on 12-speed Di2 components, you'll need to use the SM-PCE02 tool. This tool was released a couple of years ago, long before the EW-SD300 wiring standard even existed.
As a result, you need to use an EW-AD305 adapter to connect the SM-PCE02 to 12-speed bikes. They're not expensive, but it's something to be aware of.

Did you know that you can mix Di2 components from different series and categories? Mixing derailleurs is not recommended, but anything else is fair game!
