- What package and version are you using ?  
Brain fw v0.1.9

- Please, describe the issues you are seeing ?  
There is an external USB type A connector covered by a weather cap on the rear of the Brain and there is also an M12 connector labeled “IO”. I did not find anything about the IO port in the datasheet. Is the IO port compatible with USB? Is there a breakout cable for the IO port (I can fabricate one if I have more info)? If not, are there USB type A connectors that have these weather caps (assuming it’s standardized)? Thanks.

\*\* Any possible information will make the live of the community members easy to reply and provide a solution.

Thanks in advance!

The USB interface is made by Amphenol. There is a lot of potential use cases, so depending on needs you might need to use a cord grip or other method to seal the other side of the USB device.

Sealed USB to cable end, for building a custom cable, 3 lengths  
UA-30AFMM-LL7B01  
UA-30AFMM-LL7B02  
UA-30AFMM-LL7B03

This has some stock at Mouser

Regarding IO, this will likely be deprecated because the value of the IO, cost of the connector and supporting electronics has not justified a lot of attention. Because of the number of uses it is easier to push IO needs to CAN, Ethernet, or USB.
