An Engineer's Guide to USB Type-C: Power, Data, and Future Standards
An Engineer's Guide to USB Type-C [pdf]
I walk you through the essentials of USB Type-C and USB Power Delivery, explaining how this single interface now handles up to 240W of power and 80Gbps of data. We explore the evolution from USB 2.0 to USB4, clarify the roles of sources, sinks, and dual-role ports, and examine how alternate modes like DisplayPort and Thunderbolt expand device capabilities for everything from laptops to industrial tools.
With USB Power Delivery, you can now transmit up to 240W of power and up to 80Gbps of data at the same time.
