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
All design files are available on GitHub and are open source. Schematics, layout, gerbers, and example code is available under an MIT-style license.
I'm in the process of porting over the Google Chromium OS code into a standalone library for USB Power Delivery. I started with just the FUSB302-specific code. You find the github repo here. The example explains how to connect this breakout board to an Arduino. Then it reads the state of the CC pins, assuming it is plugged into a Downstream Facing Port.
The next major firmware upgrade will be a library that uses the FUSB302 library to send and receive PD messages and set states of the Type-C connector to perform all the higher-level functionality.
