Ideal para sa mga engineer, technicians, hobbyists, at mag-aaral na gumagawa sa embedded systems, DIY electronics, o device repair. Ano ang USB? Universal Serial Bus (USB) ay isang pamantayan na interface para sa pagkonekta ng mga peripheral sa mga computer at mobile devices. Ito ay sumusuporta sa: Data transfer Power delivery (hanggang 240W sa USB PD) Device charging Hot-swapping Bawat bersyon ng USB ay nagpapakilala ng bagong features: USB 2.0 : Hanggang 480 Mbps USB 3.0 : Hanggang 5 Gbps USB 3.1 Gen 2 : Hanggang 10 Gbps USB 3.2 / USB4 : Hanggang 40 Gbps Ang pisikal na mga konektor ay may iba't ibang tipo at henerasyon, ngunit lahat ay sumusunod sa mahigpit na pin assignments. USB Connector Types Overview Connector Pins Use Case USB 2.0 A/B 4 pins Hosts, printers, keyboards Mini/Micro USB 2.0 5 pins Lumang mga telepono, cameras USB 3.0 A/B 9/11 pins High-speed data, external drives Micro USB 3.0 10 pins Smartphones, tablets USB 3.1 C (USB-C) 24 pins Reversible, high-power, fast data Note: Ang USB-C ay sumusuporta sa reversibility , dual-role operation , at Power Delivery (PD) .
