One of many biggest options of USB-C apart from the bidirectional, reversible connector is USB Energy Supply. USB-PD is one thing I’ve been all for for the reason that USB Implementers Discussion board launched the specs for it. It permits units to barter for a better voltage VBus, in addition to offering info round present limits. It’s an effective way to get versatile, high-power initiatives powered up. Nevertheless, getting it arrange may very well be a ache. However with this superior FUSB302B Breakout Board you’ll be able to shortly and simply add USB-PD to any mission you’re engaged on.
Your microcontroller will talk to the FUSB302B through I2C, permitting fine-grained management over the USB connection. This chip can act as a sink or a supply, that means it’s also possible to use this breakout to construct a beefy USB-C energy provide in order for you! There are many libraries on the market to make communication with this chip straightforward. Vendor WaffleBomb additionally has their very own library for communication with the system being ready for launch and moreover has the schematic out there.
However if you wish to dig into the nitty gritty particulars of USB Energy Supply (which I extremely advocate) you can begin with the FUSB302B datasheet. Observe that this datasheet has numerous phrases which can be outlined in the USB-PD specification, so it’s good to have each paperwork useful in the event you’re leaping in toes first. This breakout additionally has the USB 2.0 information pins damaged out, so your system also can talk over conventional USB if linked to a tool that helps it. So with one single board, you’ll be able to maintain most of your energy provide and USB communication on the similar time!
