Quick-connect male USB plug, 4-pin 4p

USB-A male to 4-pin screw terminal adapter A USB-A male adapter with a 4-pin screw terminal makes it easier to build connections using the USB interface. Assemble your own cable, adapter, or custom lead without soldering. A small screwdriver is enough to open the terminal clamps, insert the wires, and tighten the terminals. This module works well in electronic projects and can be used with Arduino, ESP8266, ESP32, and Raspberry Pi. Key technical features The adapter offers a rugged design and the option to detach the terminal block from the main plug housing. Summary of the most important specs:

* Input connector: USB-A male

* Output connector: 4-pin screw terminal

* Wire installation: No soldering, screw tightening

* Compatible wire types: Stranded and solid-core

* Mechanical features: Detachable terminal block, clearly marked pins

* Housing materials: Plastic enclosure, metal contacts

Example applications Thanks to non-destructive wire mounting, this adapter is widely used in electronics workshops and diagnostics. Typical use cases include:

* Building custom USB connections in prototype circuits

* Quickly routing USB signals to screw terminal points

* Building or emergency-repairing dedicated USB cables without a soldering station

* Power and communication in microcontroller projects including ESP32, ESP8266, Arduino, and Raspberry Pi

* Easy breakout of individual data and power lines from a computer USB port for testing

Benefits Using a quick-connect male USB plug noticeably speeds prototyping and reduces assembly mistakes. Main advantages:

* Rapid installation and removal of wires without soldering

* Reliable, stable electrical connections thanks to strong screw clamps

* Intuitive termination of conductors thanks to clearly labelled pins on the housing

* Broad compatibility with many electronic devices and popular modules

* Better longevity and mechanical durability due to the terminal block being physically separable from the USB plug
