USB-OTG Setup IMG 2342
USB On-The-Go (USB OTG or just OTG) is a specification first used in late 2001 that allows USB devices, such as Tablet computer, tablets or smartphones, to also act as a host, allowing other USB devices, such as USB flash drives, digital cameras, computer mouse, mice or computer keyboard, keyboards, to be attached to them. Use of USB OTG allows devices to switch back and forth between the roles of host and device. For example, a smartphone may read from removable media as the host device, but present itself as a USB Mass Storage Device when connected to a host computer. USB OTG introduces the concept of a device performing both Host and Peripheral roles whenever two USB devices are connected and one of them is a USB OTG device, they establish a communication link. The device controlling the link is called the Host, while the other is called the Peripheral. USB OTG defines two roles for devices: OTG A-device and OTG B-device, specifying which side supplies power to the link, and ...

USB OTG Logo
Universal Serial Bus (USB) is an technical standard, industry standard, developed by USB Implementers Forum (USB-IF), for digital data transmission and power delivery between many types of electronics. It specifies the architecture, in particular the physical Interface (computing), interfaces, and communication protocols to and from ''hosts'', such as personal computers, to and from peripheral ''devices'', e.g. displays, keyboards, and mass storage devices, and to and from intermediate ''hubs'', which multiply the number of a host's ports. Introduced in 1996, USB was originally designed to standardize the connection of peripherals to computers, replacing various interfaces such as serial ports, parallel ports, game ports, and Apple Desktop Bus (ADB) ports. Early versions of USB became commonplace on a wide range of devices, such as keyboards, mice, cameras, printers, scanners, flash drives, smartphones, game consoles, and power banks. USB has since evolved into a standard to r ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Protocol (computing)
A communication protocol is a system of rules that allows two or more entities of a communications system to transmit information via any variation of a physical quantity. The protocol defines the rules, syntax, semantics, and synchronization of communication and possible error recovery methods. Protocols may be implemented by hardware, software, or a combination of both. Communicating systems use well-defined formats for exchanging various messages. Each message has an exact meaning intended to elicit a response from a range of possible responses predetermined for that particular situation. The specified behavior is typically independent of how it is to be implemented. Communication protocols have to be agreed upon by the parties involved. To reach an agreement, a protocol may be developed into a technical standard. A programming language describes the same for computations, so there is a close analogy between protocols and programming languages: ''protocols are to communica ...

Lightning (connector)
Lightning is a proprietary computer bus and power connector, created and designed by Apple Inc. It was introduced on September 12, 2012, in conjunction with the iPhone 5, to replace its predecessor, the 30-pin dock connector. The Lightning connector is used to connect Apple mobile devices like iPhones, iPads, and iPods to host computers, external monitors, cameras, USB battery chargers, and other peripherals. Using 8 pins instead of 30, Lightning is much smaller than its predecessor. The Lightning connector is reversible. The plug is indented on each side to match up with corresponding points inside the receptacle to retain the connection. In 2018, Apple began transitioning to USB-C on iPad Pros and accessories. In response to European Union legislation to standardize charging ports passed in 2022, Apple said it would comply with regulations. The iPhone 15 and 15 Plus and the iPhone 15 Pro and Pro Max, announced on September 12, 2023, became the first iPhones to use USB- ...

USB Accessory Charger Adapter
The initial versions of the USB standard specified connectors that were easy to use and that would have high life spans; revisions of the standard added smaller connectors useful for compact portable devices. Higher-speed development of the USB standard gave rise to another family of connectors to permit additional data links. All versions of USB specify cable properties. Version 3.''x'' cables, marketed as ''SuperSpeed'', added a data link; namely, in 2008, USB 3.0 added a full-duplex lane (two twisted pairs of wires for one differential signalling, differential signal of serial data per direction), and in 2014, the USB-C specification added a second full-duplex lane. USB has always included some capability of providing power supply, power to peripheral devices, but the amount of power that can be provided has increased over time. The modern specifications are called ''USB Power Delivery'' (''USB PD'') and allow up to 240 watts, with or without data communications capabili ...
