thanks!
Where can I find the pin layout and the connector reference?
I believe it is a mini B USB, but is not really sure

Yes, this I've already understood from the doucmentation.
For my I application, I will need to make my own cabling.
Any hints on connector reference are welcome

Hi tamir,
I'm also looking for more info. If you can also PM me.
I lost my cable and can't find where to buy a new one without being crazy expensive.
I'll try to solder some wires.
Thanks
Best regards
