I am thinking about connecting up my UP board to the OpenCR by using a BEC which supplies 5v and plug it into the barrel connector of the UP... As to not accidentally fry another one :( ...
So I was wondering if Robotis sells in matching cables that plug into power out connector (or 12v connector) of the OpenCR board.
I believe these connectors are (SMW250-02) connectors.
If Robotis does not sell them, do you know of a matching connector cable (or parts) that would work, that hopefully can be purchased from some place easy to get a few parts, like Amazon, or Digikey, Mouser, Sparkfun, Adafruit...
Likewise the 5v connector. I believe that one is a Molex connector. I know you supply one that converts that one to a standard 2 pin .1" connector as part of the Turtlebot 3 package. Again wondering if that cable is available or a list of parts?
Unfortunately, the SMW250-02 mating connector(SMH250-02) cable is not available in the market yet.
The cable that uses the connector is included in Bioloid Kit for its battery, but it's not sold separately.
It might be easier for you to simply replace the SMW250-02 to Molex 5267-02 or some other connector that has 2.5mm pitch for now.
If I correctly understood your second question, the cable converts Molex 5264-02 to 2.54 female header.
I apologize for the inconvenience, and bring this issue for improvement.
