The maximum allowed cross-section of the overmold boot (which is part of the connector used for its handling) is 16 by 8mm (0.63 by 0.31in) for the Standard-A plug type, while for the Type-B it is 11.5 by 10.5mm (0.45 by 0.41in).

About The Author

Unlike Type-A and Type-B connectors, female USB-C ports can accept a male USB-C plug inserted either way up, as the terminals at both port and plug are completely symmetrical. Type-C USB connectors can be used with adapters that allow the connection of various other USB types, and they are capable of transferring power and data to/from all previous generations of USB devices.

Small devices can be powered directly from the USB interface, eliminating the need for additional power supply cables. Before the Battery Charging Specification was defined, there was no standardized way for the portable device to inquire how much current was available. For example, Apple's iPod and iPhone chargers indicate the available current by voltages on the D− and D+ lines. When D+ = D− = 2.0V, the device may pull up to 900mA. When D+ = 2.0V and D− = 2.8V, the device may pull up to 1A of current. [53] When D+ = 2.8V and D− = 2.0V, the device may pull up to 2A of current.

Mini A/B - a versatile connector that can accept either mini A-type or mini B-type plugs and cables In addition to limiting the total average power used by the device, the USB specification limits the inrush current (i.e., the current used to charge decoupling and filter capacitors) when the device is first connected. Otherwise, connecting a device could cause problems with the host's internal power. USB devices are also required to automatically enter ultra low-power suspend mode when the USB host is suspended. Nevertheless, many USB host interfaces do not cut off the power supply to USB devices when they are suspended. [100]

USB3.1, released in July 2013 has two variants. The first one preserves USB3.0's SuperSpeed operation mode and is newly labeled USB3.1 Gen 1, [32] [33] and the second version introduces a new SuperSpeedPlus operation mode under the label of USB3.1 Gen 2 (marketed as SuperSpeed+ USB). SuperSpeed+ doubles the maximum data signaling rate to 10Gbit/s (later (USB 3.2) marketed as SuperSpeed USB 10Gbps), while reducing line encoding overhead to just 3% by changing the encoding scheme to 128b/132b. [32] [34] The PCI Express function of USB4 replicates the functionality of previous versions of the Thunderbolt specification. Axelson, Jan. "USB 3.0 Developers FAQ".

USB PD continues the use of the bilateral 5% tolerance, with allowable voltages of PDO ±5% ±0.5V (eg. for a PDO of 9.0V, the maximum and minimum limits are 9.95V and 8.05V, respectively). [42] The 24-pin double-sided connector provides four power–ground pairs, two differential pairs for USB2.0 data (though only one pair is implemented in a USB-C cable), four pairs for SuperSpeed data bus (only two pairs are used in USB 3.1 mode), two "sideband use" pins, V CONN +5V power for active cables, and a configuration pin for cable orientation detection and dedicated biphase mark code (BMC) configuration data channel. [27] [28] Type-A and Type-B adaptors and cables are required for older hosts and devices to plug into USB-C hosts and devices. Adapters and cables with a USB-C receptacle are not allowed. [29]As of 2023, [update] USB consists of four generations of specifications: USB 1. x, USB 2.0, USB 3. x, and USB4. USB4 enhances the data transfer and power delivery functionality with UART and RS-232 serial adapter, modem, Wi-Fi adapter, Ethernet adapter.
