What is a USB 3.1 Type C?

USB-C basically describes the plug’s shape. For example, if you use an Android phone the connector shape of the previous standard is USB-B and the flat one on your computer is called USB-A. The connector itself can support various exciting new USB standard like USB 3.1 and USB power delivery.


As technology moved from USB 1 to USB 2 and on to modern USB 3, the standard USB-A connector has stayed the same, providing backward compatibility without the need for adapters. USB Type-C is a new connector standard that’s about a third the size of an old USB Type-A plug.
This is a single connector standard that can connect an external hard drive to your computer or charging your laptop, like the Apple Macbook. This one tiny connector can be small and fit into a mobile device like a cell phone, or be the powerful port you use to connect all the peripherals to your laptop. All this, and it is it reversible to boot; so no more fumbling around with the connector the wrong way.

● Features

● USB Type-C: 8.3mmx2.5mm

● microUSB: 7.4mmx2.35mm

● And lightning: 7.5mmx2.5mm

● Therefore, I can't see the advantages of USB Type-C on handheld devices in terms of size. And the speed can only see if the video transmission is needed.

● Pin definition

It can be seen that the data transmission mainly has two sets of differential signals of TX/RX, and CC1 and CC2 are two key pins, which have many functions:
• Detect connections, distinguish between front and back, distinguish between DFP and UFP, that is, master and slave
• Configure Vbus with USB Type-C and USB Power Delivery modes
• Configure Vconn. When there is a chip in the cable, a cc transmits a signal, and a cc becomes a power supply Vconn.
• Configure other modes, such as when connecting audio accessories, dp, pcie
There are 4 power and ground, which is why you can support up to 100W.
