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 ON Semi (formerly 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

All design files are available on GitHub and are open source. Schematics, layout, gerbers, and example code is available under an MIT-style license. Click here for the board design files. Click here for the FUSB302's manufacturer's page for a datasheet or to request sample code.

For more information on USB-C, please read my overview starting with Part 1 here. I am in the process of porting code from the Chromium OS to C++ for use in embedded systems. I have a Type-C Port Manager library for the FUSB302 specifically, and worked with a colleague to produce another library for USB Power Delivery, which uses it. The current status of the code is that it working well enough to support being a Power Sink, and runs on Arduino.
