## Description

Quick solution for connecting cables to a DB25 connector without soldering, each pin has a metal terminal with a screw for secure fastening and stable contact. The insulating PCB provides solid mounting support and individual access to pins for prototyping and testing. Compatible with RS232, parallel port, and other D-SUB 25 interfaces, ideal for Arduino, STM32, or ESP32 projects.
This breakout module allows quick and solderless connection of cables to a DB25 connector (D-SUB type with 25 pins). It is ideal for prototyping, testing, or integration in projects requiring RS232, VGA interface, or other applications using 25-pin D-SUB connectors.

Usage:
Loosen the terminal screw corresponding to the desired pin, insert the wire end, and tighten the screw to firmly secure the connection. Then, insert the DB25 connector into the equipment port (computer, controller, etc.).
Attention! This module does not provide additional protection (no diodes, resistors). It is only a mechanical intermediary.
