Hi,

What is the purpose of mbed pins 37 and 38 (IF+ and IF-)? What do they connect to?

Regards,

Paul

They are alternative USB connections to the interface USB mini-B connectors. We're not convinced they are a great idea, hence the lack of promoting them, but are there incase it becomes interesting enough to support the interface connection through the DIP pins.

They should always be N/C for now.
