Reclaimer Labs have a nifty USB-C breakout board available here at Tindie.
Want to play around with the new USB Type-C connector? You’ll need a chip to manage the CC pins. This board allows you to use I2C and an interrupt line to perform all necessary USB-C functions. At the heart of this board is the Fairchild FUSB302, a Type-C port controller and BMC PHY. You can use this chip to do any and all of the following:
Determine plug orientation (normal or reversed) Determine or advertise Type-C power levels (5 V at 0.5, 1.5, or 3.0 A) Use BMC communication to negotiate USB Power Delivery Explicit Contracts up to 20 V and 5 A (100 W of power) Negotiate Alternate Modes to reuse the pins in the Type-C connector for other purposes
